I'm just getting started with OCR SDK, and I'm using PHP to send POST method with an image of a serial number, and I'm testing out letterSet and despite setting it as follows:
I still get letters returned in the XML result set. I've also been testing the RegExp parameter, and that also seems to be ignored (returning letters where only numbers are specified in the RegExp). In this case, I am expanding letterSet to include all letters and numbers and adding this regexp parameter:
What I am trying to do is have OCR recognize a serial number in the format: A?ANNNN (A=letter, N=number) where only digits can appear in positions 3-6, and only a one or two letter prefix (A-Z).
I assume that the parameters for processTextField are sent in the URL string (GET) as opposed to sending with the POST along with the image?
I did see the post about using the "Digits" language, but my requirements are more than what is contained in that language.

The issue occurs because OCR technologies are not trained well for this font. It should be fixed in the future.
We find our that both of your images could be completely recognized with the following URL: http://cloud.ocrsdk.com/processTextField?textType=handprinted
Thank you for your patience!
