Is there some documentation available how to access harfbuzz from Lua (jit) / FFI?

Patrick

Well, look at luatexdir/luaharfbuzz I have also used https://github.com/khaledhosny/harf to check %% test2-latex.tex \documentclass{article} \usepackage{fontspec} \newfontfamily\deva[Script=Devanagari]{NotoSansDevanagari-Regular.ttf}

After I understood that the format is currently only found if it is in the current folder I could test it.

sure

Like with harftex you have to use harfload and activate the harf mode to get the right output.

ok, so you want all .... \pdfvariable suppressoptionalinfo \numexpr1+32+64+128+512\relax \pdfvariable compresslevel 0 \pdfvariable objcompresslevel 0 \documentclass{article} \usepackage{harfload} \usepackage{setspace} \usepackage{fontspec} \usepackage{graphicx} \defaultfontfeatures{RawFeature={mode=harf}} \newfontfamily\deva[Script=Devanagari]{NotoSansDevanagari-Regular.ttf} \newfontfamily\beng[Script=Bengali]{NotoSansBengali-Regular.ttf} \newfontfamily\guru[Script=Gurmukhi]{NotoSansGurmukhi-Regular.ttf} \newfontfamily\gujr[Script=Gujarati]{NotoSansGujarati-Regular.ttf} \newfontfamily\orya[Script=Oriya]{NotoSansOriya-Regular.ttf} \newfontfamily\taml[Script=Tamil]{NotoSansTamil-Regular.ttf} \newfontfamily\telu[Script=Telugu]{NotoSansTelugu-Regular.ttf} \newfontfamily\knda[Script=Kannada]{NotoSansKannada-Regular.ttf} \newfontfamily\mlym[Script=Malayalam]{NotoSansMalayalam-Regular.ttf} \newfontfamily\Sinh[Script=Sinhala]{NotoSansSinhala-Regular.ttf} \begin{document} luatex with Harfbuzz: {\deva क्रर्कि} % krarki {\beng ক্রর্কি} % krarki {\guru ਕ੍ਰਰ੍ਕਿ} % krarki {\gujr ક્રર્કિ} % krarki {\orya କ୍ରର୍କି} % krarki {\taml கோ} % ko {\telu క్రర్కి} % krarki {\knda ಕ್ರರ್ಕಿ} % krarki {\mlym ക്രര്കി} % krarki {\Sinh කෙ} % ke \vskip 1em XeLaTeX: \hbox{\hskip5pt\includegraphics[width=8.5cm]{b0miX.png}} \end{document} copy the image from https://i.stack.imgur.com/b0miX.png (note \Sinh vs \sinh) -- luigi
