French punctuation spacing persists after ending the language environment

[svenper]

I am not sure if this is could be a fontspec issue, but an educated guess with otfinfo tells us that there is no French locl features that could linger.

otfinfo --scripts $(locate -i sourcecodepro-regular.otf)
DFLT		Default
cyrl		Cyrillic
cyrl.SRB	Cyrillic/Serbian
grek		Greek
latn		Latin
latn.NSM	Latin/Northern Sami
latn.SKS	Latin/Skolt Sami

\documentclass{article}
\usepackage{fontspec}
\setmainfont{Source Code Pro}
\usepackage{polyglossia}
\setmainlanguage{english}
\setotherlanguage{french}
\def\somepunct{a! b? c; d: e! \languagename\hfill}
\begin{document}

{\begin{english}\somepunct\end{english}}

{\begin{french}\somepunct\end{french}}

{\begin{english}\somepunct\end{english}}

\end{document}

@svenper

I cannot reproduce it.

[svenper]

That's odd. I tried with xelatex instead of the usual lualatex and it worked as expected. Is this really a problem with LuaLaTeX then?

[reutenauer]

Most likely with the Polyglossia code for LuaTeX. Thanks for the report, I’ll try to have a look.

[svenper]

automaticspacesaroundguillemets=false seems like it should disable this, but it does not, either for XeTeX or LuaTeX. Only Lua currently does not reset it for other languages, however.

For anyone with the same problem, a temporary workaround that completely disables french punctuation spacing (put after first loading the language):

\makeatletter
\def\noextras@french{}
\def\blockextras@french{}
\def\inlineextras@french{}
\makeatother

This is a duplicate of #49, #66, #68, #153, and #182
