Unexpected exception encountered. Not normalised type = CHAR
Hello. I'm in the process of making a scanner for my Compiler Design class using JFlex and Cup and ran into this error. Not 100% sure if it's from my own code or something else and figured I'd report the bug anyway. Attached is the output after attempting to compile as well as a link to a repo of my current project that should reproduce the bug.
Any help at all would be appreciated thank you.

This does look like an actual jflex bug. Thanks for reporting it, I'll take a closer look in the next few days.
