I don't think the 'encoding' property was ever supported by fontconfig. 
Even on my system, it's commented as "old" in 
/usr/include/X11/Xft/XftCompat.h and doesn't have a fontconfig 
equivalent in that file.

If you need fontconfig to choose a font that supports a certain glyph, 
best use the 'lang' property which fontconfig uses to indicate glyph 
coverage.

I. e. use some 'lang' value that doesn't appear in the ISO-8859-1 
version of the font.

   fc-match Terminus:lang=ru

With newer fontconfig, you should also be able to match on 'file'.
