Re: Uppercase version of ß desired

Thanks Philip. Certainly interesting, As long as postgresql and python
return something different for upper and lower case versions of these
letters and python indexing of the string picks out the characters
"properly" then it might not require a python fix for me.

What a can of worms! But at least postgresql and python do far better with
unicode than mysql and perl did! :-)
