Just to save others some time...  This script:  <a href="https://github.com/sarkamist/Tongues-Script" rel="nofollow">https://github.com/sarkamist/Tongues-Script</a>  often doesn't work on certain characters without any explanation. After a LOT of troubleshooting, I've narrowed down the issue to three primary causes:   Character name contain spaces or special characters  Character name in tongues language file > GM section contains spaces or special characters  Player's Roll20 account name/alias is same as character name   Someone should update the git README with this. It would have saved me a lot of time.
