Sign-up form incorrectly treats blank spaces as special characters, causing validation errors

[syedali237]

Describe the bug When attempting to sign up, the form validation incorrectly recognizes blank spaces as special characters. As a result, users encounter validation errors when they input a name with spaces, even though spaces should be valid characters.

To Reproduce Steps to reproduce the behavior:

1. Navigate to the sign-up form.
2. Enter the first name or last name with spaces.
3. Submit the form.

Expected behavior Spaces should be ignored, and the user should be able to submit the form without errors.

Actual behavior A validation error triggers a pop-up notification stating that only lower and upper-case characters are allowed.
