How it works

☕ → U+2615 → \u2615

Every character has a number in Unicode, its code point, written U+ and hex: “☕” is U+2615. Programming languages let you write a character by that number, which keeps source files plain ASCII. Characters above U+FFFF, like most emoji, need two \u escapes in JavaScript and JSON (a surrogate pair), or one \u{…} or \U escape where the language allows it.

  1. Find the code point é = U+00E9 · ☕ = U+2615 · 😀 = U+1F600
  2. Up to U+FFFF: four hex digits ☕ → \u2615
  3. Above U+FFFF: a surrogate pair 1F600 − 10000 = F600 → D800 + (F600 ÷ 400) = D83D, DC00 + (F600 mod 400) = DE00 → \uD83D\uDE00

Escape styles

Style ☕ 😀 Used in
\uXXXX \u2615 \uD83D\uDE00 JavaScript, JSON, Java, C#
\u{…} \u{2615} \u{1F600} modern JavaScript, Rust, Swift
\UXXXXXXXX \u2615 \U0001F600 Python, C, C++
U+XXXX U+2615 U+1F600 Unicode charts
&#x…; ☕ 😀 HTML, XML

Python and C write characters up to U+FFFF with \u too; \U is for the ones above.

Good to know

  • Unescape understands all of these: \u2615, \uD83D\uDE00, \u{1F600}, \U0001F600, \xE9, U+2615 and ☕.
