yes, this works. To see it more clearly:
$ echo $LANG
en_CA.UTF-8
$ g++ eg.cc 2>t.out
$ od -c t.out
0000000 e g . c c : I n f u n c t i
0000020 o n 342 200 230 i n t m a i n ( )
0000040 342 200 231 : \n e g . c c : 4 : e r
0000060 r o r : 342 200 230 e 342 200 231 w a s
0000100 n o t d e c l a r e d i n
0000120 t h i s s c o p e \n
0000134
and when unsetting the LANG var, the above chars become plain ascii:
$ od -c t.out
0000000 e g . c c : I n f u n c t i
0000020 o n ' i n t m a i n ( ) ' :
0000040 \n e g . c c : 4 : e r r o r :
0000060 ' e ' w a s n o t d e c
0000100 l a r e d i n t h i s s c
0000120 o p e \n
0000124
cheers, etc.
