Hi all,

I'm trying to render some text (£10.00) to an image using cfimage. However I can't get the £ character to render correctly, I just get £10.00 (see attached image).

I'm using the following code to generate the image. Any help with this would be greatly appreciated.

<cfset voucherValue = "£10.00">

<!--- Create new blank image --->
<cfset newCodeImage = ImageNew("", 450, 140, "rgb", "##FFFFFF") />

<!--- Set new text attributes. --->
<cfset attr = StructNew()>
<cfset attr.font="Arial">
<cfset attr.style="bold">
<cfset attr.size=110>
<cfset ImageSetDrawingColor(newCodeImage,"##000000")>
<cfset ImageSetAntialiasing(newCodeImage)>

<!--- Add value to blank image --->
<cfset ImageDrawText(newCodeImage,"#voucherValue#",0,115,attr)>

<!--- Save temp image --->
<cfimage action="writeToBrowser" source="#newCodeImage#">

Open in new window

Try using the unicode representation of £
<cfset vourcherValue = "\U00A310.00">

What version of CF are you running. It outputs fine for me w/CF9.0.1

Try adding a UTF8 directive explicitly first. Might be the problem.

<cfprocessingdirective pageencoding="utf-8">

Hi,
Try using the ascii chr code for the pound sign.

<cfset vourcherValue = chr(153) & "10.00">

Hope this helps.

Solved thanks guys, youve been a great help.

cfprocessingdirective didn't do anything.

After the 9.0.1 update <cfset voucherValue = "£10.00"> renders correctly.

<cfset vourcherValue = chr(163) & "10.00"> works as well (note the number is 163) and I think I'm gonna go with this as it seems a bit more complete.

Thanks again.

Not sure why. A literal copy and pasted worked perfectly for me. But if the ascii code works, then it's definitely an encoding problem.

Yeah, they also must have changed the encoding in the 9.0.1 update. Think I'll have a look at the release notes when i get chance, see if I can find anything.

Hmm.. I just tested it again and it's not UTF8 that worked. It was windows-1252

<cfprocessingdirective pageEncoding="windows-1252">
<cfset voucherValue = "£10.00">
