Right now, if I try to edit a post and my edits are deemed "minor" (fewer than 6 characters), the edit cannot be submitted. I understand this is the case in all SE sites. However specifically in language oriented sites, very short edits (even 1 character) may be important enough. For example, in this question: Different words for "German" in Russian? word "немецкий" is misspelled as "неметский" - yet I couldn't submit an edit, because it was too short.
Maybe in language-specific sites (and Russian in this case specifically) we should allow shorter edits exactly for this reason: fix misspellings. In language sites, spelling is a lot more important than in math- or programming-related ones, for example.
I understand the reasoning behind not allowing short edits, so it may not be this easy; maybe we would need to find some balance, for example, allow short edits to only users with reputation on the site above a certain number.
