No idea. But read bellow.

Depends on how you build xmlsec and libxml2.

Search LibXML2! In general, all LibXML2 calls assume that you pass
UTF8 strings. Thus, you need to make conversion to UTF8 *before*
you call LibXML2/xmlsec functions

Not sure what do you mean by this. But I am sure you can use
conversion apis from iconv or any other library directly.
