Hi all,
Firstly sorry, if the forum location is wrong. Since the scenario is related to security I just put my concern here.

Scenario: We are creating a filter to parse the request and eliminate the vulnerable characters for our application which supports languages en, fr, de. To achieve that we are creating a list of characters that can be allowed and we could do it successfully for English using a regular expression as below.

However, to achieve the same for French and German characters in form of regular expression, we couldn't get a way out. Google search didn't help much.
Any suggestions or links are highly appreciated.

Thanks in advance

Closing it late
For those who are looking for it, If I remember, we used \p{L} to consider these characters and it worked fine.
