Font standards

E16 themes have many choices when it comes to font setup.

X Font (normal/multibyte)
Fnlib
TrueType

Pango
Xft

In order for a theme to be functional on as many distributions as possible, which choice would be the most effective? Should we limit the themes here to a standard set (possibly UTF8) for the best support? If so which ones would be good candidates?

RE: the example

Hmm... on my box the -xos4-terminus-* font seems to work properly when LANG=ru_RU.iso88595 and ru_RU.koi8r but not ru_RU.utf8.
