Dealing with "characters" in C is inextricably linked with the locale. You
can avoid using the locale for encoding by using e.g. iconv to convert
between wchar_t[] and char[] then reading/writing char[] with the standard
library. But there are still issues such as collating order, numeric
formatting, etc which are locale-dependent even with wchar_t[].
