Subject: Use C locale instead of C.UTF-8 for protocol strings

The C.UTF-8 locale is not portable, so we need to use C, otherwise
we crash on other systems. We can use std::locale::classic() for
that, which might also be a bit cheaper than using locale("C").

(cherry picked from commit 0fb16c3e678044d6d06ba8a6199b1e96487ee0d8)
