Thanks xtermie. I'm not sure that is the complete picture. For example, if I look at the font drop down in PowerPoint, I see 8 sub-fonts listed in the Sego UI family:<br />
<a href="https://filedb.experts-exchange.com/incoming/2016/08_w36/1114280/Sego-Font-Family-in-PowerPoint.png" target="_blank" title="Segoe font family in PowerPoint (2 KB)"><img alt="Segoe font family in PowerPoint" class="file-block lazyload" style="max-width: 289px;" data-src="https://filedb.experts-exchange.com/incoming/2016/08_w36/1114280/Sego-Font-Family-in-PowerPoint.png" /></a>I'm then not sure your answer addresses the second screenshot I provided in my original question whereby the deck I received has some text set to use the SemiBold variant yet the text is not being rendered on the slide with the font family at all but Arial and the absence of the &quot;TT&quot; icon in the list would indicate that the SemiBold font is missing, which it's not. Finally, if I use VBA to check the name property of the text that is not rendering correctly, I get this:<br />

<pre><code class="code-1 nolinks" id="code-20-41776481-1"><span>?ActiveWindow.Selection.ShapeRange(1).TextFrame2.TextRange.Font.Name</span>
<span>Titillium Web SemiBold</span>
</code></pre>
It seems that there is more to this than meets the eye?

Can you check and see if these are all TrueType (TT) fonts? &nbsp;<br />
<br />
You can also try to clear the Font &nbsp;caches and check the results:<br />
<br />
To do this:<br />
<br />
1. &nbsp; &nbsp; &nbsp; Quit all Office applications. <br />
<br />
2. &nbsp; &nbsp; &nbsp; Click Go then choose Home. <br />
<br />
3. &nbsp; &nbsp; &nbsp; Open Library\Preferences\Micros<wbr />oft\Office<wbr /> 2011 folder and click the Office Font Cache for 2011 files.
</div>


<div>
Yes, all TTF files as per this screenshot in Windows 10 File Explorer, licensed under the SIL Open Font License:<br />

Also another method would be to opened Word as that rebuilds the Font list. Exit Word, Open PowerPoint...All fonts should show show up in Powerpoint now
</div>


<div>
Can you please try this for Windows 10:<br />
<br />

<ol type="1">
<li>Press and hold the &quot;Windows&quot; key (located between the left &quot;Ctrl&quot; and &quot;Alt&quot; keys), then tap the &quot;E&quot; key to open Windows Explorer.</li>
<li>Double-click on your local hard drive, where the operating system is installed in the left pane, then double-click to expand the &quot;Windows&quot; directory. Double-click on the &quot;System32&quot; folder.</li>
<li>Right-click on &quot;Fntcache.dat&quot; in the right pane of the Windows Explorer window and choose &quot;Delete.&quot; Click the &quot;Yes&quot; button to confirm the deletion.</li>
<li>Close the Windows Explorer window and restart your computer.</li>
</ol>
<br />
I've tried it on my Windows 10 x64 + MSO 2016 x32 device and the instructions work.
</div>


<div>
I tried both the Word and FNTCACHE.DAT removal methods (the cache file was rebuilt and remaind the same size as the one I removed) and I still only see one font in the PowerPoint and Word UIs for the Titillium family. Even more curious is that Word shows the single Titillium font with the &quot;O&quot; icon whilst PowerPoint shows it with the &quot;TT&quot; icon!<br />
<br />
I have attached a test deck showing the issue and a link to the font pack as EE won't allow me to upload a zip file containing ttf files.<br />

I agree with the comment from <a href="https://www.experts-exchange.com/members/xtermie.html" rel="ugc">@xtermie</a> that &quot;... Italic, Bold etc will be applied once you select the ... font and apply ... effect on it ...&quot;.<br />
<br />
The difficulty is that Word (and I assume other Office applications) only &quot;know about&quot; <b>Regular</b>, <b>Italic</b>, <b>Bold</b> and <b>BoldItalic</b> variants of a particular font &quot;family&quot;.<br />
<br />
So where a family has more than the four variants, how does Word decide how to choose four out of those on offer - I don't yet know the answer to this question.<br />
<br />
There is obviously some sort of algorithm, since the Arial font family has more than four variants, but (even though they all have the same &quot;family&quot; name) Word manages to group these <i>nine</i> fonts (on my Windows 10 Pro 64-bit system with Office 2013) as:<br />
<br />

<div class="bullet">
<b>Arial</b> - Regular, Italic, Bold and BoldItalic variants
</div>
<div class="bullet">
<b>Arial Narrow</b> - Regular, Italic, Bold and BoldItalic variants
</div>
<div class="bullet">
<b>Arial Black</b> - Regular only
</div>
<br />
Also shown separately (as different &quot;families&quot;, with only one variant each) are: - <b>Arial Rounded MT Bold</b>, <b>Arial Unicode MS</b>, <b>Arial_Mono</b><br />
<br />
But Word doesn't appear to &quot;group&quot; the <i>eleven</i> variants of the fonts with family name <b>Titillium Web</b> into separate groups, so how is it supposed to select four to match its standard set of four style variants?<br />
... and why doesn't it do a similar &quot;grouping&quot; to that with Arial - is it to do with the 'root' of the &quot;full font name&quot;, or what?<br />
<br />
<br />
As regards <b>OpenType</b> versus <b>TrueType</b>: OpenType is the modern 'packaging' of a font - it can contain a font which uses <i>TrueType</i> outlines, or a font which uses (PostScript) <i>Type 1</i> outlines.<br />
I guess that Word and Excel are only interested in fonts with TrueType rendering, and Excel still shows it as such, whilst Word shows the 'packaging' name?
</div>


<div>
Jamie, clarification needed.<br />
<br />
&quot;This then causes the text on the slide with one of the sub-fonts (Titillium Web SemiBold) set to be replaced with Arial.&quot;<br />
<br />
So you're receiving the deck from someone, yes? And it's as though Titillium is embedded but the subfonts are not, correct? That could again be how the font itself is constructed.<br />
<br />
Also, if the other subfonts weren't used in the deck, then they wouldn't show up in the dropdown.
</div>


<div>
Hi Echo.<br />
<br />
I am receiving the deck from a third party - yes. When checking the <b>Save Options</b>, the <b>Embed fonts in the file</b> option is not checked. Based on the client's brand guide, I downloaded and installed the full family of Titillium Web fonts. When I then rebooted Windows and opened the deck in question, the sub title of the first slide shows that the font is set to Titillium Web SemiBold (in the PowerPoint font drop down combo box) but the TT icon isn't present for it and the text in the placeholder is rendered with the theme font which is Arial.<br />
<br />
What's odd is that I assume the third party isn't having this issue as I've also got a video export of the same deck where the SemiBold font is rendering as expected. I need to check this assumption.<br />
<br />
Let me also go dig out one of my ancient font tools to see if I can see anything in the way the family is built.
</div>


<div>
&gt; What's odd is that I assume the third party isn't having this issue as I've also got a video export of the same deck where the SemiBold font is rendering as expected.<br />
<br />
Yeah, that's weird.
</div>


<div>
No idea about how &quot;embedded fonts&quot; may or may not contribute to the issue, just a bit more research on the naming and &quot;grouping&quot; of fonts:<br />
<br />
The Microsoft Typography web site includes a specification (not for the faint-hearted) of the OpenType / TrueType format.<br />
<br />
This includes a <a href="https://www.microsoft.com/typography/otspec/name.htm" rel="ugc">page</a> describing the <b>name</b> table, which details the <b>Name IDs</b> and their uses; it states that &quot;<i>... Up to four fonts can share the Font Family name, forming a font style linking group (regular, italic, bold, bold italic - as defined by OS/2.fsSelection bit settings) ...</i>&quot;.<br />
<br />
That page links to <a href="https://www.microsoft.com/typography/otspec/namesmp.htm" rel="ugc">another page</a> which gives an example (for the Arial font) of how those Identifiers should be used:<br />
<br />
<a href="https://filedb.experts-exchange.com/incoming/2016/09_w36/1114681/FontData_Arial.png" target="_blank" title="Extract from name ID example (44 KB)"><img alt="Extract from name ID example" class="file-block lazyload" style="max-width: 800px;" data-src="https://filedb.experts-exchange.com/incoming/2016/09_w36/800_1114681/FontData_Arial.png" /></a><br />
I've looked at the various fonts in the TitilliumWeb set, and constructed a similar table of the identifiers used (for Windows/Unicode-BMP (platform/encoding 3/1):<br />
<br />
<a href="https://filedb.experts-exchange.com/incoming/2016/09_w36/1114685/FontData_Titillium.png" target="_blank" title="name IDs for Titillium fonts (28 KB)"><img alt="name IDs for Titillium fonts" class="file-block lazyload" style="max-width: 800px;" data-src="https://filedb.experts-exchange.com/incoming/2016/09_w36/800_1114685/FontData_Titillium.png" /></a><br />
As you can see, <b>all</b> of the Titillium fonts have the same ID=1 value, which contravenes the guidance (whereas the Arial family has one value for the base set of four, a different value for the 'Narrow' set, and a third value for the 'Black' variant).<br />
<br />
This may explain why Office applications find it difficult to select a set of four (regular, italic, bold, bold italic) fonts from the Titillium set, and don't show the font with separate 'subsets' (as happens with Arial).<br />
&nbsp;<br />
I haven't yet looked at the flag values in the <b>OS/2</b> and <b>head</b> tables, as per the second part of the Arial example.

This might start to shed some light. I used FontCreator (for the PC) to look at some of the properties of Segoe Semibold (which does show multiple fonts in the PowerPoint UI) and Titillium SemiBold (which only shows the 'master' regular font in the UI). The Typographic Family field in the second pair of &nbsp;screenshots below might be something to do with it. Not sure if I can write properties to the fonts and retest but will have a try next.<br />

<a href="https://www.experts-exchange.com/members/JamieGarroch.html" rel="ugc">@Jamie Garroch</a> - I think that you're on the right track trying to perhaps change the ID values via a font editor.<br />
<br />
If you do this and get things working, it would be a good idea to then feed this back to the Google fonts support team, perhaps?<br />
<br />
I have an old (but probably not up-to-date version) of <b>FontCreator</b> - a very useful tool.<br />
<br />
What I'm not sure about (perhaps because my version of the application is not the latest) is how the 'text box names' (as used in various FontCreator forms) map to the entries within the various relevant OpenType tables.<br />
[My version (7.5.0 build 519) shows the &quot;<i>Typographic Family/SubFamily</i>&quot; as &quot;<i>Preferred Family/SubFamily</i>&quot; entries (on the <b>Extended</b> tab)].
</div>


<div>
... if i was changing the properties, this would be my starting point:<br />

I've changed the list order (compared with the original table) to 'group' the suggested subsets.<br />
<br />
I haven't looked in to the settings of the <b>fsSelection</b> tags (Italic, Bold, Regular) in the <b>OS/2</b> table - I assume that these probably map to the settings of the <b>Bold</b> and <b>Italic</b> check-boxes on the <b>Identification</b> tab of the FontCreator <b>Properties</b> dialogue.

A font is a particular size, weight and style of a typeface. Each font is a matched set of type, one piece (called a "sort") for each glyph, and a typeface consists of a range of fonts that share an overall design. With the advent of digital typography, font is frequently synonymous with typeface, although the two terms do not necessarily mean the same thing. In particular, the use of "vector" or "outline" fonts means that different sizes of a typeface can be dynamically generated from one design. Each style may still be in a separate "font file" -- for instance, the typeface "Futura" may include the fonts "Futura roman", "Futura italic", "Futura bold" and "Futura extended" —- but the term "font" might be applied either to one of these alone or to the whole typeface.

PowerPoint is a slide show presentation program currently developed by Microsoft. PowerPoint presentations consist of a number of individual pages or "slides" that may contain text, graphics, sound, movies, and other objects, which may be arranged freely. The presentation can be printed, displayed live on a computer, or navigated through at the command of the presenter. Slides can also form the basis of webcasts.
