subscript in alt attribute

[marbly]

How do I get superscript and subscript text in alt attribute? Do I use entities?

The text is about chemical formulas.

Well, you won't be able to do it with markup tags since ALT is plain text. Thus using the Unicode http://en.wikipedia.org/wiki/Unicode...d_superscripts or similar as a fake would make most sense though obviously the results will depend on the font and encoding, etc.

If your image is a water molicule, just do "h 2 o" versus h ₂ O

Way more info, but an interesting read: http://en.wikipedia.org/wiki/Wikiped...lity/Archive_8

Thank you!

I'm using utf-8 so I don't think there will be problems with unicode entities, I'll go that way.
