Single character task not saved unless non-visible special character is added

Description: When entering a single character as a task, it is not saved. However, if added along with a non-visible special character, it gets saved.

Steps to reproduce:

1. Open the Todo app
2. Type "g"
3. Press Enter

Expected result: Task should be saved

Actual result: Task is not saved

Additional case:

1. Type "g " (with non-visible special character)
2. Press Enter

Result: Task gets saved

Environment: Chrome browser (Desktop)

Impact: This creates inconsistent behavior and may confuse users during input.
