How to convert a literal string to regex

[Peng Yu]

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.
