Cool, I had the log running here it is as well as the encoding of the strings. I used the EncodingTools project from codeproject. The paths might look funny but they do work with regular named files. The "testFiles" directory is a symlink in the path below. But we see the same behavior w/o a symlink too.
thanks!
