Escape Quote in RegExp

Support
1

How do I escape a single quote in regexp? These attempts don't work:

$regexp(%title%, '[_#\']',)
$regexp(%title%, '[_#'']',)
2

In this case it would probably be
`$regexp(%title%, '[_#''']',)
It is 2 apostrophes to escape one and then you have 2 strings in apostrophes, one to the left and one to the right of the escaped character.

I copied and pasted that into the column value:

$regexp(%title%, '[_#''']',)

The column shows this:

[ SYNTAX ERROR IN FORMATTING STRING ]

Try this:
$regexp(%title%,'['_#''']',)

That works! Thanks! Can you explain how/why that works?
