What is the status of LuaTeX's Unicode support? According to the documentation, the 'slnunicode' library is used. However, this project is no longer under development, see
https://github.com/LuaDist/slnunicode [This library comes with zero documentation, BTW, which is quite unfortunate.] In the above repository, the corresponding source code file that holds the Unicode data, `slnudata.c`, is from 2006; this means it reflects Unicode 5.0, while the current Unicode version is 15.0. Do you use the `uniParse.tcl` script, probably https://opensource.apple.com/source/tcl/tcl-14/tcl/tools/uniParse.tcl.auto.html , to regenerate `slnudata.c` as soon as a new Unicode version gets published? It would be nice if this information gets included in the LuaTeX documentation... Werner
