This is the same bug as bug #9845. Encodings CP1257 and ISOLatin7 are used for
Lithuanian and Latvian languages. They differ only by certain symbols such as
quotation marks. Instead of umacron and Umacron there are symbols ucircmuflex
and Ucircumflex in file CP1257.enc, which belongs to package grDevices. 

To see the problem compare the outputs 

> postscript(encoding="CP1257.enc")
> plot(rnorm(100),main="\u016B\u016A")
> dev.off()



This bug appears only in Windows environment with Lithuanian locale, since only
then CP1257 is used as default encoding.

Changing [uU]circumflex to [uU]macron in file CP1257.enc fixes the problem.
