filnaming and multilanguage files

short question here on filnaming and multilanguage files.

Is there any stnadard or imdb naming convention to mark a movie's title for a file with non-english audio, in order to make it instantly "recognizable" to the reader and to scrapers alike. I mean there are movienames that are equal in title for the english and the german, so i look for a way to "visualize" just that? Like with a "[DE]" suffix or s.th. But everything i tried seems to get scraper requests confused in too many cases.

And while beeing at it, how would you guy's treat multilanguage movies? In the case i described above i kept the title naming in german, but it's a shame that by doing this i don't instantly see that there's also english audio on board.

I also tried to have the titles named "germanMovieTitle - englishMovieTitle (date).extension", but that really got a mess when scraping files

..hm...noone interested..

Well i still simply add another question, like today it crossed my mind, that maybe it would be a good idea to have MC ignore characters in between, let's say, square brackets, when scraping the title. Are there any characters i could use for that?

e.g.
somemovietitle (date) [whateverElse].ext

so that "whateerElse" would simply be ignored... ?
