“ć” is letter. Maybe not in Latin1, but certainly is in Unicode.
This is far from first time that I have issues like this. I recently bought the promo bundle on macupdate.com and entered the same letter in my last name, which gave me 12 serial numbers based on “Aleksandar Vacić” because it converted the letter into HTML entity.
To PayPal’s credit, at least they don’t allow this to happen so I don’t have to see a display as ugly as this:

This also happened when I bought TopStyle Pro few years ago, through eSellerate.
What is it with these web sites?
Are they all based on decade old code snippets, before the wide spread use of Unicode and UTF-8? How can any current website allows itself the luxury of not using Unicode, in this era of globalization?
Amateurish, to put it mildly.





Well, mildly put, they simply do not care.
Prime target sites of that kind are English speaking (and writing) folks, not rest of the us.
I really do not understand why that attitude (in era of 2008, when adding UTF8 support _is trivial_) but it is there and it seems that will stay a little bit longer.
Same here. Got so many shareware apps with the umlaut in my name ruined. Or missing. Or replaced with a question mark. Even on big apps like VMWare Fusion or Parallels (which is useless by the way, just in case you were pondering which to pick).
IMO they are fully aware of this situation but as long as we don’t complain they won’t get into the huge task to port all code and database to UTF-8.
