You make it for the file in question, not the translation unit. That means it
won't affect #includes and terminates at the end of your #inclusion.

This also means preprocessors need to understand that for the # lines.

# 1 "foo.cpp"
#pragma encoding "utf-8"
"this is UTF-8"
# 1 "foo.h"
#pragma encoding "latin1"
"this is Latin1"
# 3 "foo.cpp"
"this is again automatically UTF-8"

Which could get funny with lex outputs... then again, I don't think lex can
handle multibyte.
