With the world going forward internationally, this seems a step backward.

May I suggest to add xmlModuleOpen8() workhorse which

* operates on UTF-8 Unicode
* is called by libxml and
* could optionally be called by xmlModuleOpen().

This keeps the current API for those who call it directly and adds
Unicode to all who call it indirectly.

If you decide for LoadLibraryA, I strongly suggest to raise an error if
non-ASCII characters are passed in. Otherwise application end users who
load their own extensions may have really hard times figuring out why
the are failing to load.
