German umlaute in fixture names, test names and test messages are not handled properly

It appears that Google Test can not handle umlauts - at least they do not show up in the test result file - sample result file:

ResultFileWithUmlauts.txt

When running tests, GTA falls back to console parsing for the according tests since their test name is not correctly read from the broken XML file, and thus the according test case is not found. When debugging tests, GTA does not have this option since we are not able to access the debugged process' standard output (that's why we cannot print test output when debugging tests). Therefore, the test is labeld as skipped.

Maybe we should just accept this, but I do not like that test results differ between running and debugging tests... Therefore, one suggestion would be to not support umlauts at all and mention that in the docs.

Maybe we should also file a bug against Google Test.
