[Rdfapi-php-interest] Need help with german Umlaut

[Susanne B. <ma...@su...>]

Hello.

I am from Germany and I need to use german Umlauts in my rdf-file. I tried to use 
<?xml version="1.0" encoding="utf-8"?>

as header but I always get this error:

Fatal error: RDFAPI error (class: parser; method: generateModel): XML-parser-error 9 in Line 71 of input document. in C:\Program Files\xampplite\htdocs\IRLscreen\rdfapi-php\api\syntax\RdfParser.php on line 2225


Line 71 is the line there the first u Umlaut is located. If I choose ISO-8859-1 as encoding I get no parse error but the u Umlaut is A with tilde followed by "a quarter".

Can anyone help me please?

Greets
