One way is to train with only those characters you want recognized. That method works for command-line usage too.

if someone has an answer to this one, i am wondering if it is possible to "force" the recognition to only given characters (Known before recognition, Eg. "0 to "9" and "<".

inside of the wrapper or of any public function) if there is a way to
disable special characters? I only need A-Z 0-9 and special characters
is ALWAYS wrong which i occasionally get.
