For the most of it, libxml2 uses UTF-8 strings internally and relies on
the ordinary C standard library functions to interact e.g. with the file
system. It largely ignores the distinctions between _UNICODE, _MBCS, and
"ANSI" one may encounter in programming Windows-specific applications.
Practically you may run into trouble asking libxml2 to open certain file
names, and you have to manually convert UTF-8 strings from libxml2 to
whatever suits your application best, but it shouldn't matter much more
than that.

It's more likely you are mixing runtimes, e.g. your libxml2 might have
been compiled with /MT while your application uses /MDd or something to
that effect.
