Q: Thai bibliography apa7 I try to make a bibliography in Thai with apa7 form. Is it possible without citation?
My attempt
\documentclass[a4paper]{report}
\usepackage{polyglossia}
\usepackage{fontspec}
\usepackage[style=apa,backend=biber]{biblatex}

\XeTeXlinebreaklocale "th"
\XeTeXlinebreakskip = 0pt plus 0pt
\defaultfontfeatures{Scale=1.23}
\setdefaultlanguage{thai}
\setotherlanguage{english}
\newfontfamily{\thaifont}{Laksaman.otf}[%
ItalicFont={Laksaman-Italic.otf},%
BoldFont={Laksaman-Bold.otf},%
BoldItalicFont={Laksaman-BoldItalic.otf},%
Script=Thai,%
Scale=MatchLowercase,%
WordSpace=1.25,%
Mapping=tex-text,%
]

\addbibresource{ref.bib}

\begin{document}
\nocite{*}

\printbibliography
\end{document}

I'm using Texstudio version 4.2.3.

A: Your document compiles with errors for me on Overleaf when using XeLaTeX. The resulting PDF does show the bibliography. The error complains that there is no .lbx file for Thai language. Seems there isn't one: https://github.com/plk/biblatex/tree/dev/tex/latex/biblatex/lbx
See this if you want to use unsupported language:
What is the most appropriate way to configure biblatex for use with an unsupported language?
