Re: Certain characters cause exception when type in editor

Hi Benno,

Thank you for the reply. I am familiar with this blog page and have used
the referenced GitHub repo for guidance earlier on the project. However,
even using the lexer and parser code from the repo does not work either.
The running instance of NB will no longer display the .r file. It still
executes just fine, but I cannot edit the file to see if the characters
will be accepted.
