  Not the right way the problem is at the very beginning:

  The problem is there. It's not permitted to do this. The tree is
expected to be maintained in UTF8. xmlEncodeEntitiesReentrant() 
will escape "special" chars like '<>&' but will NOT try to handle
charset conversion.
  You need to convert first the string to UTF8. There is a function
exported from encoding.h to do IsoLatin1 to UTF8 encoding. Check
    http://xmlsoft.org/encoding.html
  for libxml2 encoding support choices and description.
