About Unicode escape sequence
Unicode escape sequences convert a single character to the format of a 4-digit hexadecimal code point, such as \uXXXX. For example, "A" becomes "\u0041".
Unicode non-BMP characters represented as surrogate pairs do not fit in the 4-digit code point, so they are represented in the following format for each programming language.
| Programming language | Format | Conversion result of "😀"(U+01F600) |
|---|---|---|
| Java, JS(ES5) | \uXXXX\uXXXX | \ud83d\ude00 |
| Swift, JS(ES6+), PHP, Ruby | \u{XXXXX} | \u{1f600} |
| C, Python | \U000XXXXX | \U0001f600 |
