This File you can parse in IE or Firefox without any problem and the UTF-8 Format should allow the umlauts. And the problem is the Validation from the SQL server, he don't whant to accept this files.
I have tested some more and the result is:
1. When the encoding ist like "iso-8.....", then the SQL server saves the file but instead of the umlauts "ü" he writes "?" into the database and when I am extracting the file from the Server its now an "?" and not a "ü".
nope because of he inserts the Table now but, have you seen the text in the Database the "ü" is now a "?" and when you extrackt it from the DB back to an XML File now its an "?". :-/ i have tested this allready
and yes UTF-8 supports umlauts because all other valitdation programms say its an valid dokument.
but you have the same problem if you use some umlauts?
