I think you want to keep your non english character as well (in other words you only want to remove punctuations like ./- etc) Your best bet is to use replace function if you want to consider non english characters. The only drawback is that you will have to specific each character individually. For example: if no dot (.) is desired in output, insert dot as given below (same thing for the dash). I'm no expert on this but I thought this may give you some ideas..

Solved: Replacing certain characters in a string - Alteryx Community
June 13, 2024 - The replace function works in a similar way in that you define ([Target field], ‘target string’, ‘replacement’), and we can therefore just tell Alteryx to replace all remaining _ with a space ‘ ‘. Hope this helps! If you’d like to learn a little more about RegEx then there’s plenty of great materials online - can be a very powerful tool if you’re dealing with strings containing regular patterns that you need to tackle!

String Functions
The replace parameter can be either a specified value as shown below or a marked group, like "$1". Make sure that marked groups are wrapped in double quotes. icase is an optional parameter. When specified, the case must match. By default icase=1, which means ignore case. If set to 0, the case must match. REGEX_Replace("Don't reveal your Social Security number, 123-45-6789","\d{3}-\d{2}-\d{4}", "CLASSIFIED") returns Don't reveal your Social Security number, CLASSIFIED.

HI @Idyllic_Data_Geek,
Building on what @Emil_Kos built and the comments by @apathetichell. I was able to get this to work in a single Multi-Field Formula tool using the formula
REGEX_Replace([_CurrentField_], "[,!\(\)#';\\/@]", ' ')
This uses the exit (escape) to tell RegEx to find the special characters instead of using the special characters. For more information on Perl Syntax used by RegEx formulas and tools, I recommend this guide on Community: https://community.alteryx.com/t5/Alteryx-Designer-Knowledge-Base/RegEx-Perl-Syntax-Guide/ta-p/1288
