double i problem

[Serlaix]

well... I don't know if I'm right putting this problem here, but I need a reply
the problem is with the sollux quirk, that I'm trying to put these setting
regexp: [iI]
replace with: \1\1
but there's a problem, when I test it says that is an error, and I don't know what to do.

Try
regexp: ([i,I])
replace: \1\1

That worked for me.

many thanks :DD
it worked!!

I was able to fix it by adding parenthesis
like this...
([iI])
\1\1
