Hello,
How do I discard all special characters in the Polish alphabet (ąćńółżź) in a form field?

I use Custom Keystroke Script:

event.rc = /^[ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0-9]*$/.test(event.change);

OR

event.rc = /^[\w]*$/.test(event.change);

 

Unfortunately, it still allows to enter these characters (ąćńółżź).

Not sure why the first code doesn't work, but this does:

event.rc = /^[a-z,0-9]*$/i.test(event.change);

Update - the above scripts, however, work correctly. I tested them in the Foxitreader application and they do not work there, but they work properly in the Acrobat DC. So the cause is a bug in the Foxitreader application.

Thank you for your help 🙂
