Code review comment for lp:~jameinel/tarmac/non_ascii-750930

I'm not sure how I feel about this. GCC is using the fancy quotes because the locale you're compiling under is en_US.UTF-8 presumably (as you are presumably running this as a live logged-in user). If GCC runs under the C locale, it uses pure ASCII for error/warning messages. And, as you pointed out, this will still fail if under a UTF-8-incompatible locale, such as Russian KOI8-R. I wonder if a better solution might be to force the locale to be C inside tarmac.
