After searching for two hours without success, I'll ask it here, maybe someone knows:

I'd like to create ordinal letters (for example for "1st" "2nd" ...).
Are there official unicode values where I can place them?

I found some, like "m" "n" etc. but I'm still missing "s" (and some others), and they are not contineous but spread all over the ranges...

So I'm neither sure whether the ones I found are intended to be used for that purpose, nor I know where to place the others I haven't found yet.

Thanks for your help (again and again...)
Sebastian
