Only if you want it to (by using LANG). This is no behavior exclusive to 
fontconfig.

(Normally that would make sense too, because if you want localized help 
messages, you would need fonts with the proper character sets.)

Otherwise use either LC_MESSAGES to just localize the messages, or 
LC_CTYPE to just localize font selection, this should even work with 
fontconfig-2.9.0 (and earlier) FcDefaultSubstitute-based mechanism.
