functx:escape-for-regex
Escapes regex special characters
Description
The functx:escape-for-regex function escapes a string that you wish to be taken literally rather than treated like a regular expression. This is useful when, for example, you are calling the built-in fn:replace function and you want any periods or parentheses to be treated like literal characters rather than regex special characters.
