I don't this this is a valid case either. The problem is only when you need to use such strings with the :exec command (as that involves concatenating strings), but if you are just passing on the string to Vim functions, you don't have to worry about escaping single quotes. Even when you need to concatenate and use a regex, you still need to only escape the single-quotes and backslashes and use it in the \V mode, something like: '\V'.escape(substitute(regex, "'", "''", 'g'), '\') -- Hari __________________________________________________ Do You Yahoo!?
