Encoding windows-1255

Question

I have created an apex class which created an xml using:

xmlW.writeStartDocument('windows-1255','1.0');

but I get the following error:

Underlying stream encoding 'UTF-8' and input parameter for writeStartDocument() method 'windows-1255' do not match.

How can I create an XML with another encoding than UTF-8?

Answer 1

It is currently not fixed in SF.

You can vote for the idea, but in the current moment you have nothing else to do, than leave UTF-8 encoding.
