    Message : xkbcomp: Add Unicode code point escape sequence \u{NNNN} Unicode code point escape sequences `\u{NNNN}` are replaced with the UTF-8 encoding of their corresponding code point `U+NNNN`, if legal. Supported Unicode code points are in the range `1‥0x10ffff`. Note that we will reject the `U+0000` NULL code point, as we reject it in the octal escape sequence `\0`. This is intended mainly for the upcoming feature to write keysyms as UTF-8 encoded strings. It can be used for various reasons: - avoid encoding issues; - avoid issue with font rendering (e.g. Asian scripts); - make white space or zero-width characters more readable.

  • Added [Unicode code point] escape sequences `\u{NNNN}`. They are replaced with
the [UTF-8] encoding of their corresponding code point `U+NNNN`, if legal.
Supported Unicode code points are in the range `1‥0x10ffff`. This is intended
mainly for writing keysyms as [UTF-8] encoded strings.
