The Xlib documentation says "in the form supported by the host C
language environment", which I take to mean "whatever the OS normally
uses for wchar_t".
If __STDC_ISO_10646__ is defined, then wchar_t is ISO-10646. Other
than that, I'm not aware of any standard mechanism to determine the
system's encoding of wide characters.
