We are from Russia, so we need to use cyrillic letters in 'came from' field.
We tried just to type 'тест' in that input and after we clicked on 'Update the bucket profile' they were transformed to the Unicode sequence (like that - '%u0442%u0435%u0441%u0442'). But it didn't work - the bucket was empty.
Then we tried to use percent-encoding (URL encoding). We wrote '%D1%82%D0%B5%D1%81%D1%82' and this was transformed to 'тест'. It didn't work either, though document.referrer contains '%D1%82%D0%B5%D1%81%D1%82'.
We've never had that issue before, so after further investigation we made some modifications on the configuration tool to accept cyrillic letters.
Just go back and edit the behavior and input 'тест' on the came from field. This time it will be correctly saved to the proper format and your bucket should work when the referrer contains the '%D1%82%D0%B5%D1%81%D1%82'.
Thanks for your feedback, it was helpful to us to improve the tool.

This was a very specific case, as the browser automatically converted the cyrillic letters to UTF-8 according it's configurations of character encoding, even if you don't do it. So we updated the application to cover cyrillic letters both escaped or unmodified and the URL with your test case is now working just as expected.
Thanks for your feedback.
