hi

consider this code:

i want to set utf-16 as internal encoding for domdocument
because source data is utf-16 encoded

$doc->encoding = "UTF-16";

but my output for web is handled by:

iconv_set_encoding("internal_encoding", "UTF-16");
iconv_set_encoding("output_encoding", "UTF-8//TRANSLIT//IGNORE");

or can be handled by

echo iconv("UTF-16", "UTF-8", $xmldata);

so the output is utf-8 encoded but the xml declaration says:

<?xml version="1.0" encoding="UTF-16"?>

so $document->encoding property should work as how it works now, but it should not affect the xml declaration

in plus you should provide an alternative to set $xmlEncoding (make it non-readonly)

i'm sorry for my english... i hope you accept this request!
thank you
