Questions
Why does an emoji become two \u escapes in JavaScript?
JavaScript strings and JSON store text as UTF-16, where characters beyond U+FFFF (most emoji) take two units, called a surrogate pair: 😀 is \uD83D\uDE00. Modern JavaScript also accepts \u{1F600}.
Which escapes can be decoded?
U+ code points, \u and \u{…} (JavaScript and JSON), \U (Python), and HTML entities like 😀, in any mix. CSS escapes and UTF-8 bytes are decoded when you choose that format, since they could be ordinary text.
What is the character table for?
It lists each character with its code point, UTF-8 and UTF-16 codes and kind. It reveals look-alike and invisible characters, like a zero-width space or a Cyrillic “а” posing as a Latin “a”.
Is it free? Do I need an account?
It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
