physi:

I believe the AM means that you can use the keep_encoding option to retain your original string data.

However, I think that the problem is that you're specifying the encoding as ISO-8859-1. If I understand properly, that means that you're telling XML::Twig that there's no Unicode data in your input. However, you have an entity in there. Since the ampersand is special, XML::Twig is properly escaping that so that when it decodes in the future, that it generates the proper output.

If you specify a unicode encoding, I expect that XML::Twig will then read the string as a unicode character, and then emit it properly when it rewrites the file.

Disclaimer: What I know about unicode you can write on a pinhead with lipstick.

When your only tool is a hammer, all problems look like your thumb.

Thanks roboticus.

Same misunderstanding of unicode on my side :-)
but even if I delete the encode line, I get the same result. I think this might be end in not using keep_encoding and then susbstitute the resulting Umlaute like ÖÄÜöäü with their encode_entities_numeric Values :-(
