Groovy’ strings delimiter can be either ’ (single quote) or " (double).
You can escape a single quote within a string delimited by single quotes.

For example, you can have : ‘blah blah' blah blah’.
My problem is that the escaped quotes ' is always detected as end of the string.
So the last single quote is interpreted as the start of a new string which imply the highlighting is wrong for the reste of the file.

Is there any way in a user defined language to exclude ' as string delimiter when ’ is a string delimiter ?

Thank you in adance for your help
