Perhaps, the only question is what letters should we use? Latin letters? 
But, for example, 90% of people in Russia don't understand all letters

but this may cause problems with fonts in captcha generators.

As Sergei Golovan said there is a problem in Tkabber: the message window 
should not pop up. You may want to get more info from Tkabber developers 
in the corresponding list.
