I want to make a glossary with glossaries-extra package and use Cyrillic characters as entries labels. Everything works fine with XeLaTeX. Clickable links refer to exact glossary entry. But in LuaLaTeX links doesn't work properly. They refer to wrong place.
Entries with Latin link works fine in every case.
MWE:

documentclass{article}

usepackage{polyglossia}  

setmainfont{Liberation Serif} 



usepackage{hyperref}



usepackage[nonumberlist]{glossaries-extra}



newglossaryentry{язык}{ name={язык},

                         sort=lowercase{язык},

                         description={Система общения людей.}}



newglossaryentry{компьютер}{ name={компьютер},

                              sort=lowercase{компьютер},

                              description={Вычислительная машина.}}



makeglossaries[main]



begin{document}



    section*{Словарь}



    printglossary[style=list,title={}]



    forallglossaries{thistype}{section{Glossary `thistype'}

    forglsentries[thistype]{thislabel}{gls{thislabel}. }}



end{document}

Is there a way to get right links in pdf with LuaLaTeX?

As Ulrike Fischer described the problem is that non-ASCII characters are dropped by pdf@escapestring. To avoid this, you can change pdf@escapestring to encode Unicode characters in UTF-8:

documentclass{article}

usepackage{polyglossia}  

setmainfont{Liberation Serif} 



usepackage{hyperref}



usepackage[nonumberlist]{glossaries-extra}



newglossaryentry{язык}{ name={язык},

                         sort=lowercase{язык},

                         description={Система общения людей.}}



newglossaryentry{компьютер}{ name={компьютер},

                              sort=lowercase{компьютер},

                              description={Вычислительная машина.}}



makeglossaries[main]



makeatletter

longdefpdf@escapestring#1{%

directlua0{%

 oberdiek.pdftexcmds.escapestring("luaescapestring{#1}")% Almost like the original one, just omit "byte" to keep all characters.

}%

}

makeatother



begin{document}



    section*{Словарь}



    printglossary[style=list,title={}]



    forallglossaries{thistype}{section{Glossary `thistype'}

    forglsentries[thistype]{thislabel}{gls{thislabel}. }}



end{document}

Not a solution but an explanation. The problem is hyperref. hyperref uses with lualatex pdf@escapestring to convert the name to something that can be safely used as a destination in the pdf. But the current implementation of pdf@escapestring handles only ascii, everything else is simply dropped. And this means that glossaries creates for the two entries the same destination glo: On the terminal you can see the warning

 warning  (pdf backend): ignoring duplicate destination with the name 'glo:'

when trying this document:

documentclass{article}



usepackage{hyperref}



begin{document}



makeatletter 

pdf@escapestring {glo:компьютер}



pdf@escapestring {glo:язык}





hypertarget{glo:компьютер}{blub}



hypertarget{glo:язык}{bla}
