  You need to find the way to convert your input. UTF-8 can handlle the
full Unicode range.

  Any Unicode code point has a representation in UTF-8, the answer should
be yes.

  This is not compatible with the mailing-list policy. Please get rid of
this footer because we will make any communication made to this list publicly
available and searchable even by non-subscribers to the list. Tell your
management and IT hierarchy that this is incompatible with working with
Open Source projects ! You may get private support for libxml2 code but
I exect this to be only made as part of commercial support contacts (with
whoever may want to sell such support).
