All unicode charcters can be expressed in a UTF-8 encoding in XML
in that sense UTF-8 is a "complete" encoding for XML
unicode table is here:
http://unicode-table.com/en/
If your editor does not support entering UTF-8 straight from the keyboard, you can always use numeric character entities
eg. for unicode codepoint 178 (superscript 2) use
²

Open in new window

If you do it that way, your character is also safe for encodings that don't support the full unicode

Hi;

Thanks for the reply. I checked codepoint 178 in the link, but it was another character. can you attach a screenshot by circling it?

My question also involves superscript of, say, letter k. Is that one there too?

Regards.

note that there are two ways of expressing numeric character entities
numeric decimal
²

Open in new window

or numeric hexadecimal
²

Open in new window

(note the X after the # for the hex number)
both are the same character only expressed differently
please try to add the 178  numeric entity in a html and check in the browser, you will see I am right, that definitely is superscript 2

Your question did not mention "k" etc. But if you look at the table, you will find at least teh subscripts expressed... hint: you can search the table through the search box using the word "subscript" by example
the subscript "k" is
 ₖ

Open in new window

but that is an more obscure font... in order to visualize it you will need a font with full support of unicode
