No Native Language Support in browser started from shell prompt

[Dr Bean]

With qutebrowser and Microsoft Edge started from a cygwin shell prompt, 
there is no Native Language Support.

Started from a cmd prompt,

"c:\Program Files\qutebrowser\qutebrowser.exe" https://ja.wikipedia.org/wiki/%E8%A5%BF%E6%97%A5%E6%9C%AC%E3%81%AE%E5%A4%A7%E5%AD%A6%E4%B8%80%E8%A6%A7

qutebrowser has Chinese and Japanese support.

But in cygwin neither qutebrowser, started with cygstart or
as /cygdrive/c/Program\ Files/qutebrowser/qutebrowser                  
https://ja.wikipedia.org/wiki/%E8%A5%BF%E6%97%A5%E6%9C%AC%E3%81%AE%E5%A4%A7%E5%AD%A6%E4%B8%80%E8%A6%A7

nor Microsoft Edge as default browser started with cygstart, enjoy NLS support.

Of course the IME are working in the mintty bash shell and 'screen' 
sessions.

I don't understand.
