Vietnamese alphabetical sorting with glossaries-extra

Question

I've got a problem with sorting glossary entries in my paper as follows: đ is supposed to come before p, but glossaries-extra doesn't recognize that.

Here is my MWE:

\documentclass[12pt, a4paper, oneside]{book}
\usepackage[utf8]{vietnam}
\usepackage[automake]{glossaries-extra}
\makeglossaries
\newglossaryentry{bien dia phuong}
{name = biến địa phương, 
description = {some texts go here}
}
\newglossaryentry{bien toan cuc}
{name = biến toàn cục, 
description = {here is some texts}      
}
\newglossaryentry{bien phi dia phuong}
{name = biến phi địa phương, 
description = {there texts go.  
}
}
\newglossaryentry{bien}
{name = biến, 
description = {label for an information}                
}
%\addcontentsline{toc}{Forewordt}{#1}
\begin{document}
This is \gls{bien dia phuong} \gls{bien phi dia phuong} \gls{bien toan cuc}
\gls{bien} là một nhãn để gán giá trị. 
\printglossary[nonumberlist]
\end{document}

And here is the output with p coming before đ:

I want to sort it in alphabetical order:

biến 
biến địa phương 
biến phi địa phương 
biến toàn cục

If you read the glossaries package documentation, you'll see that the package recommends that you use xindy for indexing:

If you are writing in a language that uses an extended Latin alphabet or non-Latin alphabet it’s best to use Option 3 (xindy) or Option 4 (bib2gls)...

This was already pointed out to you in a previous question of yours. Just add the xindy package option to glossaries-extra to use xindy, and refer to the glossaries or glossaries-extra package documentation if you need more details on using xindy.

\usepackage[automake, xindy]{glossaries-extra}
