hmm that is really quite strange, you cannot see the 'alpha' in your browser... and we are both using IE 5.5, mine worked and yours didn't...
okay [here]α[/here] can you see that alpha? in this post? if not what do you see nothing?
I agree that it won't be recognised as its only ascii figures that are recognised and aplha isn't on that, but why you cannot see it in your browser.. hmm I am going to check the settings to see if there is anything there..
If you go here and go to section A2.Entity Sets, you can download the Unicode entity sets. They have all the hex codes you need to include Unicode glyphs in your [X]HTML. The Symbols set is the one you are after.
