<br>
So you expected to find utf8 in the text value instead of the unicode ( 233 is the same in latin1 and unicode btw )<br>
But that is not how the xmerl works. It represents the characters in unicode iso-10646.<br>
<br>
Here is an example to get you a utf8 output. Bin is your binary.<br>
<br>
Term = binary_to_term(Bin).<br>
{Content,_} = xmerl_scan:string(binary_to_list(Term)).<br>
UnicodeChars = xmerl:export([Content], xmerl_xml).<br>
Utf8Bin = unicode:characters_to_binary(UnicodeChars).<br>
<br>
I guess you could scan the xml structure (Content) and convert the text values<br>
to utf8 strings. But that would complicate the process when you want<br>
to format the output.<br>
<br>
Why do you want to have utf8 in the values ? unicode is much more<br>
generic and you select the encoding on the way out!<br>
