Words with no unicode chars in it works fine, as soon as the mention name or word contains a unicode sign ("umlaut") it breaks at that character.

Ah yes, sorry about that. I'll try to get this fixed soon.

Please see if the new unicode support meets your needs. You will need to reinstall the karma add-on in order to see the changes go into effect. You won't lose karma data by reinstalling.

To reinstall, first uninstall the addon in your group or room(s), then add it again with this installer URL:

https://hipchat.com/addons/install?url=https%3A%2F%2Fkarma.hipch.at%2Faddon%2Fcapabilities

Or enter this integration URL manually into the private integration dialog:
