> Creating changelog.xml file doubles UTF-8 encoding if the git comment information is already UTF-8 format. For example: if property outputEncoding is set to ISO-8859-1 the output is (shown as od dump):

> The result of UTF-8 encoding is that scandinavian umlauts are garbled. Code C3 B6 is the right for the "ö"-letter.
> The ISO-8859-1 format would do for the site documentation but since the file changelog.xml header says ISO-8859-1 encoding, rest of the process fails to process umlauts.
> I modified class ChangeLogReport method writeChangelogXml() by commenting out issue MCHANGELOG-86 writer change:
> {code}
>         PrintWriter pw = new PrintWriter(new BufferedOutputStream(new FileOutputStream(outputXML)));
>         pw.write(changelogXml.toString());
>         pw.flush();
>         pw.close();
>         // MCHANGELOG-86
> //        Writer writer = WriterFactory.newWriter( new BufferedOutputStream( new FileOutputStream( outputXML ) ),
> //                                                 getOutputEncoding() );
> //        writer.write(changelogXml.toString());
> //        writer.flush();
> //        writer.close();
> {code}
> It might be there is double escaping in Writer since couple of lines above the change set is created with encoding information:
> {code}
>             String changeset = changelogSet.toXML(getOutputEncoding());
> {code}
> However, this is just a wild guess since I did not check out implementation of changelogSet.toXML() or writer.write(). It could be also something different in version control access since MCHANGELOG-86 was a SVN issue and here we got with GIT.
