> Invalid language code exception

> Project: Tika
> Issue Type: Bug
> Components: ocr

> Original Estimate: 1h

> There is a regex in TesseractOCRConfig.setLanguage(String language) which
> attempts to validate the language being set. Unfortunately it does not allow
> you to set some languages that are valid for tesseract.
> For example:
> TesseractOCRConfig config = new TesseractOCRConfig();
> config.setLanguage("chi_tra");
> This throws an IllegalArgumentException because of the '_' in the language
> name. "chi_tra" is a valid tesseract language code.
> Need to update the regex to allow '_' character.
