Description
Special characters were transformed to regular expression so it was giving an error if they were invalid.
Added \ to escape the special characters. For example, if we write * in the input, internally the component will transform the value received to \* so it will be valid.
Added new test.

About the implementation, I have created a regular expression with the special characters that are giving error. Then I have converted it to string and created an array with each character. It is needed to remove the duplicate characters from the array because the function .toString() is literally converting the regular expression in a string without removing the characters /, [ and ] that are used to create de regular expresion (example, const a = /[a-z]/).

Screenshots
Created a new function to transform the value:
