Suppose I have $string='().',

If I want grep such string, I should use regex /\(\)\./. Is there a
subroutine to convert '().' to '\(\)\.'?

You should read the docs for regular expressions.
Especially the bit about the \Q operator.
I'm sure it will be most helpful.

Please refrain from asking us to read the docs to you, it
is getting tiresome...

perldoc perlreref

Has a section named "FUNCTIONS".

That would probably be a good place to look for functions
having to do with regular expressions.


perldoc -f quotemeta
