I just wonder if it's a regular error?

It means that one of the character you used is not valid.

A clear example:

result += texŧ[index]

see the ŧ? It is what throws the error, not sure what its in your case. It could be that one of your colons is not an actual colon

I don't get an error, so i can't pin it down.

Thanks a lot. I rewrite them and it works. Looks like it's just some random mysterious errors.


#4

a character which doesn't have a valid ascii value, good it works now :slight_smile:
