Fontconfig (and Xft) are only interested in fonts with a Unicode encoding, 
fontconfig explicitly skips .pcf fonts which are encoded in some other way.

It would be possible to hack fontconfig to support koi8-1 encodings, but 
you'd also have to hack it to discover the PCF encoding through FreeType,
something which would require digging through the PCF private data 
structures from FreeType.
