How to convert text to Unicode

  1. Type or paste text (or switch to "Codes to text" and paste escapes).
  2. Choose how to write the codes: U+, \u, HTML, CSS, UTF-8 bytes…
  3. Copy the result, and check each character in the table.

Why one character can be several codes

Emoji above U+FFFF are written in JavaScript as two \u codes (a surrogate pair), and take 4 bytes in UTF-8. Some symbols that look like one character are several: a flag is two letters, and 👍🏽 is a thumbs up plus a skin tone. The table lists every code point, which also reveals invisible characters.
