Unicode Inspector
Code points, UTF-8 bytes and hidden characters.
0 code points
Iteration is by code point, so surrogate pairs (most emoji) appear as one row with two UTF-16 units. Handy for hunting zero-width spaces, BOMs and look-alike characters.
About this tool
Inspect any text character by character: code point, UTF-8 and UTF-16 encodings and category — hunt zero-width spaces, BOMs and look-alike characters.
