Inspect text or decode U+
Each mode has one documented grammar.
Paste · inspect · copy
See the exact values behind text that only looks simple.
UnicodeLens preserves the original sequence and shows one row per scalar with U+ notation, decimal value, UTF-8 bytes, UTF-16 units and a direct escape.
No account, upload, normalization, character database, grapheme guess, saved input or public result link.
Three explicit steps
Choose the direction, validate the complete value, copy evidence
Reject invalid surrogates
No replacement character hides the source defect.
Copy exact sequences
Visible U+ and byte output is copied unchanged.
Private text debugging
Useful when strings, storage and rendering disagree
- Explain why one emoji uses two JavaScript string units.
- Copy exact U+ values into a bug report or test fixture.
- Compare UTF-8 byte size without uploading private text.
- Distinguish precomposed and combining sequences.
Exact values · local inspection
Reproduce the sequence in UnicodeLens
Paste the text or strict U+ tokens, run one explicit operation, and compare code points, UTF-8 bytes and UTF-16 units without uploading or normalizing the value.
