If we have a universal character set we can also have a universal
collation and special collations for some languages. I mean a base
collation class that handle everything (including Czech and Chinese)
and some derived classes for languages with special characters

Because Czech and Chinese characters don't cross they can be
handled independently. Do you see a problem if Czech and Chinese
strings are sorted properly but all Chinese is placed after all
This case is not different from current situation when russian (and
I quess Czech) characters are sorted after all latin.
