Handling Tab Characters in Appian Text Fields

I conducted a test where I copied a tab character from Notepad and pasted it into an Appian text field. Appian recognizes the tab character as a special character rather than treating it as empty spaces.

How can I configure or validate this so that Appian treats tab characters as empty spaces? Any insight would be appreciated.

Can you somehow visualize this? Some Screenshots?

In the "Objet" field, I performed the test mentioned above using the tab key, and it did not validate as empty as expected.

Can you share the code of that validation?

Be aware that whether a TAB is considered empty or not, very much depends on the specific use case. So a general solution is not possible. But you can easily add your own save logic that removes any entered white space.
