Full report JSON
How it works
Different characters can look alike: Latin a and Cyrillic а are distinct. Unicode skeletons map such characters to a common comparison form; even ASCII m can map to rn. A skeleton is a comparison key, not a recommended spelling.
What you can do
Inspect occurrences and UTF-16 offsets, compare a second string, and export a complete JSON report. The readable suggestion keeps ordinary ASCII and emoji joiners; the separate skeleton view follows the pinned Unicode confusables mapping and NFD normalization. Mirror and upside-down use approximate glyph substitutions and reverse grapheme order. Emoji maps supported Latin letters/digits; other text is preserved. Review variants use Unicode confusables and keep the same case-sensitive skeleton; they may repeat and are not a security assessment. Maximum100variants and250000output units.
How to use it
- Paste a string and optionally a second one, such as paypal and pаypal. Choose suggestion, skeleton or full report.
- Run and inspect the original code points and offsets in the report. Matching is case-sensitive. Copy only after reviewing any suggested substitutions.
Errors and limits
The report uses Unicode confusables 18.0.0. It does not implement a complete UTS #39 identifier profile, domain registration policy, script restriction system or security assessment. Invisible characters are reported, not silently deleted.
Up to 10,000 UTF-16 input units, 250,000 output units, a 1 MiB UTF-8 file and 20 seconds per run. Reports use machine-readable JSON field names.
Mirror and upside-down use approximate glyph substitutions and reverse grapheme order. Emoji maps supported Latin letters/digits; other text is preserved. Review variants use Unicode confusables and keep the same case-sensitive skeleton; they may repeat and are not a security assessment. Maximum100variants and250000output units.
Frequently asked questions
Does a different skeleton mean a string is safe?
No. Fonts, context, bidirectional text and application rules also matter. Matching skeletons indicate a comparison worth reviewing; different skeletons cannot certify an identifier or link as safe.
