combine_tessdata ./eng.

[John Nilson]

I'm trying to build a greatly simplified version of the existing eng tessdata. By simplified I'm removing any punctuation and trying to train tesseract to only recognize AlphaNumberic English characters.

In learning the steps I need to take I'm trying to just run combine_tessdata on the existing eng. training files in tessdata but I can't even do that. Is that even possible?

Here's the output I get when I run combine_tessdata.exe in the tessdata directory:

C:\Program Files (x86)\Tesseract-OCR\tessdata>combine_tessdata eng.

Combining tessdata files

Error opening unicharset file
