You've spent weeks writing pristine code, achieved that mythical 100% test coverage, handled every edge case known to humanity... and then some user decides to put πŸŽ‰πŸ’€πŸ”₯ in the name field. Your entire validation layer just got obliterated by three Unicode characters.

Because apparently, while you were busy testing for SQL injection and XSS attacks, nobody thought to ask "what if someone just... doesn't use letters?" Your regex that confidently checks for ^[a-zA-Z]+$ is now weeping in the corner while your database tries to figure out how to sort "John Smith" and "πŸ’©".

Fun fact: Emojis are stored as multi-byte UTF-8 characters, which means your VARCHAR(50) field might actually only fit like 12 emojis. But sure, your tests passed. Your beautiful, emoji-less tests.
