How to use Unicode
- 1. Paste text. Homoglyphs show as distinct code points.
- 2. Read U+hex and UTF-8. Useful for debugging mojibake.
- 3. Compare NFC/NFD. Normalization matters in filenames and IDs.
- 4. IDNA. The URL parser shows the hostname form.
About this tool
Looks-the-same is not the-same. A Cyrillic а in an email domain is not Latin a. Inspecting code points is how you catch that without a lecture.
Names
The Unicode Character Database names are not shipped (too large). You get hex, UTF-8, and category.
Invisible
Format and control characters are marked so they cannot hide in a 'empty' string.
Code examples
escape
"\u0041"
