glossaries-extra package cyrillic characters issues in LuaLaTeX

Question

When I use glossaries-extra with cyrillic characters in LuaLaTeX, I get two issues:

1. different line spacing in glossary and abbreviation;

2. incorrect sorting in the index for Cyrillic words.

Please refer to the below MWE, for an example, which compiles to the document provided at the end of this question.

I am use MikTex in Windows 10 with option JAVA_TOOL_OPTIONS="-Dfile.encoding=UTF8". In TexStudio use this command: bib2gls.exe -g --tex-encoding utf-8 % .

How might I be able to resolve this issues?

Thanks so mach.

% !TeX program = lualatex
% !TeX encoding = utf-8
% !TeX spellcheck = ru_RU

Answer 1

With grouping in the index, the simplest set-up is to auto-group on case-insensitive letters:

group={auto},
sort={letter-nocase},

The package can do much more powerful output than that, though. For me, I will have to read the manual fully and see the examples.
