Hi, my work is to recognize license plates, and sometimes, tesseract recognize some special characters. I need to 'ban' those characters : '/' , '|' , ',' .

May I have some help ?

Sorry if my english is bad,

Thank you,

Guillaume

Search for whitelist / blacklist in forum for ways to restrict the characters.
