BUG : comment symbol is applied inside a double quote string

[AlexDep]

Hi, I noticed a bug in the code formatting the character "/" followed by "\" to make it stringable looks like is detected as the start of a comment and so the whole editor becomes highlighted.

letterIDs = str("ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789$&<>*+@/\\", specialCharacters);

Best
