Others ⇒ How to spellcheck multi-language LaTeX files?

[user49915]

Let's take as an example the following file in UTF-8:

Code: Select all

Außenwirkung
Nutzungsfälle
\foreignlanguage{USenglish}{behavior}
\foreignlanguage{UKenglish}{behaviour}
%%% Local Variables:
%%% mode: latex
%%% ispell-local-dictionary: "german-new8"
%%% coding: utf-8
%%% End:

It is \input from another main file, which contains \usepackage[USenglish,british,french,norsk,dutch,latin,german,ngerman]{babel}
I typically use emacs 26.1 for editing with aspell 0.60.7-20110707 for spellchecking (but I'm ready to change my habits if there's a better solution for spellchecking). The German words are checked without problems (of course, you might wish to add them to your local dictionary if they are not in the global one). The English words are problematic: each time I run M-x ispell-buffer, they show up as wrong. Is there any way to automatically check also the \foreignlanguage parts using the proper dictionary? As of now, flyspell-babel is unfortunately dead or at least seems dead to me (cf. http://texwelt.de/wissen/fragen/25319/w ... zum-laufen).
