Vertical colon and semicolon in traditional chinese

[hungtzuchang]

Unlike Japanese printing, vertical colon and semicolon in traditional Chinese should be centered but not rotated.
Example:

Result from Chinese-JFM code

% !TEX TS-program = lualatex
\documentclass{ltjtarticle}
\usepackage[]{luatexja-fontspec}
\setmainjfont[TateFeatures = {JFM = {zh_TW/{quanjiao,vert}}}]{NotoSerifTC}
\begin{document}
測試：；，。「」
\end{document}

Please add Language = Chinese Traditional option like

% !TEX TS-program = lualatex
\documentclass{ltjtarticle}
\usepackage[]{luatexja-fontspec}
\setmainjfont[TateFeatures = {JFM = {zh_TW/{quanjiao,vert}}}, Language = Chinese Traditional]{NotoSerifTC}
\begin{document}
測試：；，。「」
\end{document}

when using Noto/Source Han fonts.

I'll add it to the document in the next version.

Thanks! This works for NotoSerif-TC and Kaishu from Taiwanese MOE. However, this does not work with LXGW WeiKai TC. Does this have to do with some specific font features?

% !TEX TS-program = lualatex
\documentclass{ltjtarticle}
\usepackage[]{luatexja-fontspec}
\setmainjfont[TateFeatures = {JFM = {zh_TW/{quanjiao,vert}}}, Language={Chinese Traditional}]{LXGWWenKaiTC-Regular} %{TW-MOE-Std-Kai} %{NotoSerifTC}
\begin{document}
測試：；，。「」我？」
\end{document}

I didn't test for it... Maybe I'll have to ask @lxgw for help.😢
