Filter for Titles with two apostrophes

Hi

I can use the following RegExp to Filter for Titles with open and closed brackets : "$if($eql($regexp(%title%,\(.*\),),%title%),yes,no)" IS no

but when I try to find Titles with two apostrophes it doesn't work:
"$if($eql($regexp(%title%,'.*',),%title%),yes,no)" IS no

I thought the problem might have something to do with filtering for the same character but this expression finds Titles with two "z"
"$if($eql($regexp(%title%,z.*z,),%title%),yes,no)" IS no

Any help would be appreciated. Thanks in advance.

Cheers

See eg.g. here:

Maybe the problem is the apostrophe as a "Character with Special Functionality".

Do you ask for

as in
My Title has one' and another' apostrophe
or in
My Title has a double "quote" similar as two apostrophes

Thanks for your vour very fast reply. I'm trying to filter for two apostrophes that could be anywhere in the Title not double quotes.

Would this work:
"$if($eql($regexp(%title%,$char(39).*$char(39),),%title%),yes,no)" IS no

Thanks for your help. I used an extra quotation mark as suggested on the page you linked to and it works. Thanks again
e.g. "$if($eql($regexp(%title%,''.*'',),%title%),yes,no)" IS no

Your solution works too. Thanks
