highlighting encoding issue

[getagrip]

Hi,
when I query solr (trunk) I get "numeric character references" instead 
of regular UTF-8 strings in case of special characters in the 
highlighting section, in the result section the characters are presented 
fine.

e.g instead of the German Umlaut Ä I get ä

Example:

<arr name="attr_content">
<str>
Vielfachmessgerät
</str>
</arr>

<lst name="highlighting">
<arr name="attr_content">
<str>
<em>Vielfachmessger&#228;t</em>
</str>

Any hints are welcome.
