Code

All POSIX systems have langinfo.h and CODESET.

Browse Source 
We don't need configure probes for HAVE_LANGINFO_H (it is implied by
!WIN32), and we don't need to consider systems that have it but don't
define CODESET (that was for OpenBSD in commit 81cca218, but it has now
had it for 19 years).
