I have implemented a single-width display option for mintty 
(https://github.com/mintty/mintty/issues/964).
With this feature enabled, CJK characters are rendered single-width.

While this may appear alien for terminal users who are used to the 
established dual-width paradigm, some people may in fact prefer it, as 
advocated and visually motivated in 
https://gitlab.freedesktop.org/terminal-wg/specifications/issues/9#note_406682.

In order to support locale-consistent width handling with this option, 
I'm proposing another locale modifier "@cjksingle" which triggers this 
behaviour for the wcwidth/wcswidth API. I've prepared a patch which I'll 
send to the newlib list.

Thomas
