libunicode 0.8.0

On February 17, version 0.8.0 of the library for C++ (C++20 standard) was released. libunicode. The project is being developed by a team of terminal emulator developers. Contour and is distributed under the Apache 2.0 license.

Library Features:

• support for standards Unicode 17.0:
  • UAX #11 East Asian Width,
  • UAX #24 Unicode Script Property,
  • UAX #29 Unicode Text Segmentation,
  • UTS #51 Unicode Emoji;
• API for obtaining Unicode properties;
• SIMD optimization of certain functions (using std::simd or std::experimental::simd if available);
• optimized conversion UTF8 UTF32;
• equivalent to the wcwidth function (int unicode::width(char32_t));
• text segmentation by graphemes, characters, emojis, and scripts;
• case conversion and string comparison;
• high-level text segmentation API suitable for implementing text shaping.
• test coverage for most capabilities of the library (character width and segmentation).

Also included is the console utility unicode-query for detailed information about strings.

Change log:

• added functions:

• support for Emscripten added;
• the prefix is_ added to some testing functions.
