Summary description: Unicode bidi algorithm implementation for various LuaTeX formats
Announcement text:
There was some extensive work for this version. * Support for directional isolates was added * The implementation now passes all the tests in [BidiTest.txt](https://www.unicode.org/Public/UCD/latest/ucd/BidiTest.txt) and [BidiCharacterTest.txt](https://www.unicode.org/Public/UCD/latest/ucd/BidiCharacterTest.txt) * There are now functions which operates on Lua strings, not just nodes * The Lua and TeX APIs were extended * The core Lua module can be used in plain Lua as well The API can be considered stable now. The code has diverged from the original ConTeXt implementation due to the extensive changes and additions made in this version.
This package is located at https://mirrors.ctan.org/macros/luatex/generic/unibidi-lua More information is at https://www.ctan.org/pkg/unibidi-lua
Thanks for the upload. For the CTAN Team Erik Braun

unibidi-lua – Unicode bidi algorithm implementation for various LuaTeX formats
This Lua module is an implementation of the Unicode Bidirectional Algorithm, based on the ConTeXt project's implementation, adapted for use in various LuaTeX formats. The core Lua module also works with texlua and plain Lua.
