Hi Vli, I think you should test this on something similar to your actual text, not on the alphabet or random strings. With real text you are not going to see () or <> that may be mistaken for a O.
The sequence of characters may influence the output, in other words try it on real text. You can also blacklist the characters you do not need. To be honest, the result does not seem bad to me. Special characters are the most difficult ones. Also this font is not easy to read, look at the M letter for example. If you can, change the font or try to capture the image at higher resolution before cleaning it. What language is zth? This looks like latin text, did you try eng?
