Running a system with Shift JIS may introduce security vulnerabilities 
because parts of the system will disagree where string literals end, due 
different interpretations of the 0x5c codepoint.

I think we should add a command line argument to localedef which turns 
off returning exit status 1 for locales which are not ASCII-compatible.
