Quick Googler Updates:
Codepage 1252 is used for all of the Americas and all of Western Europe, including Iceland. 1252 doesn't cover Eastern European languages (1251), Cyrillic (1250), nor does it do Turkish (1254). The Baltics have their own special codepage 1257.
What really sucks is that even the new MS SQL Server 2005 still doesn't do UTF-8!
That's some serious fuckwittedness, despite their having some seriously non-fuckwit people working in their I18N department... on UTF-8.
