I’ve posted this before, but it might have been overlooked as it was in a mixed up context.

The syntax highlighting issue arises when a regex uses quantifiers, i.e. * or + or {3,} etc.

Example:
Two regex matches are active, all string and comment matches are disabled.

″.*?″ regex match 1/2
%%.*$ regex match 2/2

Issue:
EmEditor stops matching ″.*?″ as soon as it encounters %%.*$, even though the regex match for ″.*?″ has not yet been completed.

Would this be difficult to fix?
Because it is a serious limitation. One could write significantly more accurate syntax highlighters than what is currently possible.

Your observation is correct: highlighting with regex allows overlapping.
