Some characters look like they went through a shredder, an invisible space, a zero-width joiner, a regional flag built from two codepoints. The only way to know what a string actually contains is to inspect every character.
Inspect each character’s codepoint, UTF-8 bytes, and plane and block, right in the browser. Use it on pasted user input, hidden trailing characters, and strings that refuse to match a regex despite looking identical.
Try it now: open the free tool, runs 100{ddff9936f8333f09603555df7bd6492034f3a4a35de784276d3cf3d66166a113} in your browser.
Bottom line: inspect before you store, invisible characters break data silently.
Your turn: use the tool free here, no signup, nothing leaves your device.
