Invisible chars

[rrrrrex]

If the first char of note is russian (maybe other languages too), the next line become buggy,
For example, i can type:

Кто лучший
я

But i can't make it like this:

Кто лучший
i

The first char of second line is invisible until i type second char.

Type Привет->Привет
Go to the next line
Type 1 ->nothing
Type 2 ->12

The problem is that the first line starts from russian char. I can write WПривет and the next line will be ok.
