Is '\' Legal in a Terminal Rule?

[ballcoach12]

The following rule generates an error in the grammar editor:

terminal S_BYTE_CHAR_STR returns string:
 	'\'' S_BYTE_CHAR_VALUE* '\''
 ;

The second backslash causes the following error: Unexpected character value: ->\<-. Do I need to escape this character somehow?

Hey @ballcoach12,

I believe our internal string terminal rule doesn't allow escaping. You can either use "'" or the corresponding regex (which it will get transformed into anyway) /'/.

We simply don't support escaping characters in strings yet. I created #885 for this.
