Why You Need a Unicode Character Checker ?

Have you ever copied text from a website or document, only to find strange formatting issues, broken code, or unexpected behavior? The culprit could be invisible Unicode characters—non-printable symbols embedded in text that affect processing, security, and even AI detection.
