After LPS-91985, non-alphanumeric characters can be added to field names.
This is too lenient, and it also causes some breaks in our tests.

Steps to reproduce:

1. Go to Content > Dynamic Data Lists > Add a New Data Definition.
2. Add a text field to it.
3. Click the text field > Settings, edit name to ` or ! and save.

Expected result:
Field name can not be saved and have a message: Please enter only alphanumeric characters or underscore.

Actual result:
Non alphanumeric characters field name can be saved.

It's better to allow non-ASCII (Unicode) alphanumeric characters, like áéőű and the like, but prohibit any other characters.
