So you have to convert your informations from iso-8859-1 to utf 8 because the internal represenation of

  This is a confusing statement since it did not specify the context.
The original mail was clearly for parsing, not for tree operations. This
is not required for parsing. This is required for tree operations.

As far as I understand, libxml2 takes care of the conversion automatically
in case the enoding attribute of the XML declaration contains one of the
encodings that are directly supported by libxml2.

  Right ... at parse time. 
  It's not an "attribute"
  If the encoding is not supported parsing will simply fail as required by
the XML spec. "directly" is wrong since libxml may use the iconv library
to do the conversion for encodings which are not supported directly by
libxml2 code.

If I understand the docs
right, this should be the case for ISO-8859-1.

  Right at parse time. Wrong when editing the tree.
Whatever the encoding of the serialization, any modification or query of the
parsed tree myst use UTF-8.

Conclusion: There should be no need for explicit conversion in case
ISO-8859-1 is used.

  True for parsing only.
