This function detects and removes invisible characters (such as zero-width spaces, non-breaking spaces, and formatting marks) and unwanted spaces to prevent storing unintended or hidden characters in the database. By ensuring that only clean and valid text is saved, this function helps maintain data integrity, consistency, and accuracy across the system.
It supports configurable options to either check the entire string or limit detection to the beginning and end, allowing flexibility based on specific validation requirements. This ensures that data remains clean, readable, and free from hidden formatting errors that could cause inconsistencies in processing or display.
