Multi lingual issues

OK, this has got to be resolved.

I am using 2.8.2 and as of yet can not find a solution to the problem of using other languages in posts. I am frequently quoted in foreign (to the US) magazine and need the ability to refer to them. This even applies to some western-European chars.

Here is a brief summary of all I tried:

1) Using native TinyMCE to insert chars – converts them to ???
2) Using FCKEdit – same result
3) Removing UTF8 from Php config – creates many other problems with characters in the blog, but does let me insert most other languages.
4) Converting chars with converters to Unicode, which yields a result similar to “Комисията за защита на личните данни ” (not sure if this will show here, but those are Russian letters converted to a format of &#abcd where abcd are numbers. – auto converts them again to ???? upon posting.
5) Using the anyfont plugin, which sometimes works, but only if I upload individual TTFs for foreign languages, and sometimes is not good enough.
6) needless (?) to say, <span style and <span lang definitions make NO difference what so ever.
