---------------------------------

             Summary: Invalid language code exception
                 Key: TIKA-2231
                 URL: https://issues.apache.org/jira/browse/TIKA-2231
             Project: Tika
          Issue Type: Bug
          Components: ocr
    Affects Versions: 1.14
            Reporter: Peter Weiss
            Priority: Minor


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.
