It's been reported that the three font families (Nimbus Mono, Nimbus Roman, and Nimbus Sans) with the Cyrillic glyphs are missing the Cyrillic small letter SCHWA (afii10846/uni04D9). We should check with URW whether that's an oversight (or a mistake on our part).
Created attachment 11860 [details] URW release The original bug fixed with a URW release but Chris found a glyph missing (regression) "afii61352", "Numero Sign", Unicode 8470 (decimal). This release reportedly fixes this bug and the missing character.
These fonts resolve the missing glyph(s) issues. Committed in: http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=67aad480
