non latin identifier based autocompletion - vim

Question

I am using vim with YouCompleteMe plugin, which is awesome except the fact it has no support of unicode completion as is written here and here.
I switched to vim from sublime text and i am completely excited with vim. But the fact i dont get autocompletion of words which contains (or wholly constructed) with non latin characters drives me crazy because i am writing a lot of documents in latex and use russian keyboard layout with vim's langmap option.
I dont know if there is any way to get autocompletion of my native locale (russian) words.
I played a little with encodings and tried cp1251 as fileencoding and encoding but get no result.
Could you tell me if it is possible ?
The default vim's complete (which is triggered by pressing <C-x> <C-n>) is working but it is very inconvenient to press such a long combination when you need to complete several hundreds words in a day.
I dont want any complicated completion as i understand that it is nearly impossible with the current implementation of vim. I want identifier based completion -- complete with words that were already typed in current document.
I googled but found nothing.
I would greatly appreciate any information related to my problem.
Here is my .vimrc:
