langremap doesn't work for Cyrillic letters #3018
Description
This is a basic langmap from Cyrillic to Latin letters:
set nocompatible
set langremap
set langmap=оj,лk
nnoremap j gj
nnoremap k gk
Pressing j or k in English layout correctly moves through visual lines, pressing о or л does not, it moves through physical lines.
To compare, try langmap for Latin letters only, such as:
set nocompatible
set langremap
set langmap=hj
nnoremap j gj
In this case both h and j correctly move through visual lines.
