The locl feature of FreeSerif is a bit problematic (but I’m not sure if 
it’s the only issue here, not having enough time to test thoroughly).

FreeSerif (I tested with the version on CTAN) is a bit inconsistent in 
its glyph naming. In the attached screenshot you see the incriminated 
locl feature of FreeSerif Italic which defines

becyrillic  → serb.be
tecyrillic  → serb.alt_te
decyrillic  → cyrillic.alt_de
gjecyrillic → cyrillic.macedon_gje
pecyrillic  → uni04E3
gecyrillic  → imacron

and in salt (not in the screenshot), there is

shacyrillic → serb.alt_sha

The convention on glyphnaming is, that the base name is before the dot 
and the suffix specifies the variant 
(http://sourceforge.net/adobe/aglfn/wiki/AGL%20Specification/). Thus 
it’s expected that the glyphs be named becyrillic.serb, decyrillic.alt etc.

The replacements of pecyrillic and gecyrillic however are buggy. 
pecyrillic is replaced by uni04E3 which is the cyrillic i with macron 
and gecyrillic is replaced with latin i with macron. When copy/pasting 
from a pdf they may get pasted exactly as these i’s with macra (which in 
my superficial tests with XeLaTeX actually happens). This is the same 
issue as with LinLibertine which I described in my last mail.

Best regards,
Georg
