letterSet does not restrict recognized characters

Hi all,

I wanted to ask a question about letterSet option. I'm trying out recognition of handprinted textfields and came across this.

I'm exactly using an option letterSet=ABCDEFGHIJKLMNOPQRSTUVWXYZ, but on output I still get characters recognized as 2, }, ~, - etc. I wanted to use letterSet option together with textType=handprinted, markingType=simpleText and writingStyle calling the method processTextField.

Shouldn't letterSet strictly limit the recognized characters only to what was set in that argument?

Thanks in advance for all your help

    This was a bug on our side - we used to incorrectly set internal OCR parameters. This bug has been fixed and the fix has been deployed.
