Confusable Handle Detector
Flag the hidden and look-alike characters lurking in a handle or brand string: the spoofing tricks and display bugs you cannot catch by reading.
What it flags
- Zero-width characters.
- Mixed-script look-alikes (a Cyrillic letter passing as Latin).
- Right-to-left and bidi override characters.
- Unexpected non-ASCII.
- Stacked combining marks.
How to run
Pass a handle or string. Read-only.
Good to know
Mixed-script and non-ASCII detection are heuristics, so a legitimate non-Latin brand will trip those, which are advisory.
