Question about translations

Hi, i’m new in this community so i don’t know how to talk directly to you.
I’ve update my latest translate for the italian language, so i think i’ve finished.
Anyway i’m asking why sometimes there’s a \ between two words, like “isn’t”, and sometimes don’t.
It’s a problem if it’s without? Because, after the last beta update, i checked for some mistake in my language but it’s ok even without the \

I believe that it doesn’t matter.
The backslashes are needed there, but the translation system will add them on its own if you don’t. So I would say don’t worry about that but I’ll need a confirmation from @petr-urbandroid
