Unicode Inspector
Inspect text at the code-point level, check UTF-8 bytes and normalization, and find invisible or bidirectional controls that can hide text or spoof filenames.

Why invisible characters matter
- Zero-width characters can hide text inside a name, URL or code snippet.
- Bidirectional controls (LRO, RLO, PDF, isolates) can visually reorder text and disguise file extensions.
- Unicode normalization changes how equivalent sequences are stored. NFC is the usual choice for storage and comparison; NFKC also folds compatibility characters.
- This inspector is informational. Removing controls can change the meaning of legitimate right-to-left text, so review the result before saving it.
