It is defined in libR.so which is presumably what 'rpy' uses (you haven't 
said what rpy is), provided R was built with --enable-mbcs (the default if 
there is enough OS support - another thing you failed to mention was your 
OS).

gannet% nm -pg lib/libR.so | grep utf8locale
001ef824 B utf8locale

Look like your rpy installation is mixed up.  I presume R itself runs, in 
which case I suspect rpy is pointing at the wrong libR.so.  Maybe it needs 
updating for current R?

Suggestion: ask programming questions on R-devel as the posting guide 
says, and send 'rpy' questions to the maintainer (as the posting guide 
says), or its mailing list (if it is the project on Sourceforge, it has 
one).
