Crash with dutch compound word #12
Description
Hello, When trying to check the word tijdsgebonden(time bound) I get a crash. I just ran the check.rs example but with This dictionary.
In Dutch ij can be just one char ij. I think that this might have something to do with it. Though that ij char is not what I typed. Another thing that might be important is that tijdsgebonden is a compound word. It seems to panic in a check related to compound words. Just tijd as input does work.
Thanks in advance
Edit:
This is on the current master branch.
Linux x86_64 6.12.74-1-lts
