This pull request corrects the regular expression used for username validation to correctly recognize hyphens (-).
Changes Made:
Changed the regex pattern from ^([a-zA-Z0-9.-@])+$ to ^([a-zA-Z0-9.-@])+$.
Reason for Change:
In the previous regex, the hyphen (-) within the character class was interpreted as a range operator, not as a literal character. This caused usernames with hyphens to be incorrectly marked as invalid. By escaping the hyphen (-), the regex now correctly recognizes it as a literal character. This ensures that usernames containing hyphens are validated properly.
Points of Verification:
Confirmed that usernames containing hyphens are now correctly recognized and pass the validation. Verified that other characters (letters, numbers, underscores, dots, and at signs) are still being properly validated.
