Re: Marking Up Mathematical Symbols

I hate to say it, but images with good ALT tags are probably the 
safest bet...unless screen readers have improved a lot.

When I was testing equations a few years ago, JAWS was saying 
"question mark" for Unicode math symbols (e.g. theta), so I had a 
perfectly encoded, standards-compliant Web site that was useless on a 
screen reader.

See Snell's equation on

Maybe you could use Math ML with hidden graphics with ALT tags if you 
want to move ahead tech wise.

My two cents
