Questions tagged [unicode-escapes]

Use this tag for questions related to Unicode Escapes, a Unicode character Escape sequence represents a Unicode character.

Quoting the MSDN page:

A Unicode escape sequence represents the single Unicode character formed by the hexadecimal number following the "\u" or "\U" characters. Since C# uses a 16-bit encoding of Unicode code points in characters and string values, a Unicode character in the range U+10000 to U+10FFFF is not permitted in a character literal and is represented using a Unicode surrogate pair in a string literal. Unicode characters with code points above 0x10FFFF are not supported.

Notice that is used in its general meaning, thus you are encouraged to tag your question with the corresponding programming environment as well.
