Displaying non-Western fonts

I recently switched from Windows to the Mac and since I live in
Tbilisi, Georgia I need to deal with many web pages with text in
Georgian (kartuli) or Russian (Cyrillic). When using Windows XP these
fonts generally display automatically as long as the relevant font is
installed.

On the Mac I have downloaded and installed more than 40 Georgian
fonts. I have no trouble displaying and using them to write do***ents
with MS Word or TextEdit. But with web browsers these non-Western
fonts just show up as a string of "????".

I am sure there must be a simple answer, but after some hours of
searching I have not discovered it.
