Limitations

This detector was designed for handling small texts (< 20 characters). It will probably not work reliably for longer text sequences. As it relies on dictionaries, if a word is missing or mispelled, the detection will fail.

Contributing

If you want to add a new language, or improve an existing one, add more words to the respective dictionary in the dictionaries folder.
