  Unfortunately, they don't make it very clear that nl_langinfo(CODESET)
has to be consulted first if what's necessary is the codeset in effect
at the moment. There are a lot of other nl_langinfo categories you can
query with nl_langinfo(see langinfo.h in the ref. given below). Anyway,
the most authorative reference to POSIX system is Single Unix Spec. v3
(aligned with POSIX IEEE 1xxx) available at
http://www.opengroup.org/products/publications/catalog/un.htm
(follow the link for C955 and search for 'nl_langinfo', 'locale',
'setlocale', 'langinfo.h', etc)
