Sorry, I missed that. Try checking for errors from chdir to determine when and why it fails.

I just read the documentation for the Cyrillic module: It seems that it's not intended to help you translate the user input strings to unicode. It appears to be a way for you to use Cyrillic in your scripts. However, I've not finished my coffee this morning, and I find the documentation a bit difficult to read.
