OCR does not recognize isolated numbers

John Saygnavong 1

Whenever I send an image like the attached one, I only get the word REV back but not the number 1 that's under it. More unique number shapes like 2, 3, 4, etc. are usually recognized but the number 1 is rarely recognized.

Another example of an isolated number that doesn't get correctly recognized:

This should be a 0 (zero) but comes back as the letter O.

Another example, this case with zeros where the font is a bit square, but only the standalone zeros are missed.
