Re: [Jython-users] I can only input a character with java.lang.System.console().readline() in Chinese or Japanese language

[Chris C. <Chr...@ac...>]

The screen shot (rather than a copy/paste) was very useful. The good 
news is that I know what you want/are trying to do.

You want to use the Microsoft CMD window to run console Jython scripts 
with a Chinese locale (cp936, see 
http://msdn.microsoft.com/en-us/library/windows/desktop/dd317756%28v=vs.85%29.aspx 
and http://en.wikipedia.org/wiki/Code_page_936 ).


The bad news is that it is not possible. The Microsoft CMD does NOT 
support UTF8, you simply can't use utf8 reliably in a CMD window. You 
really want cp936 support (to match the desktop locale settings) but 
Jython does NOT support CJK either (http://www.jython.org/faq3.html 
claims it would but it was not implemented, see 
http://bugs.jython.org/issue1066 for more info, the good news is that a 
future release should have something).

I did knock up an NIO based codec (very simply it worked fine for 
Japanese, it would take 2 mins to make a cp936 one), there was no 
interest at the time, see 
http://article.gmane.org/gmane.comp.lang.jython.user/8665/match=jython+2.5.1+various+encodings+support+lookuperror+unknown


The options as I see it are:

  * set the encoding to cp936 (which is what your desktop is using), and
    create a cp936 codec (based on my nio encoding experiment or some
    other mechanism, see last two options)
  * use jythonconsole (it looks cool, I've not had chance to play with
    it yet) with utf8, http://code.google.com/p/jythonconsole/
  * use mintty, I've had mixed success (things work but CTRL-C behavior
    is odd) using this with utf8 applications under windows but I've not
    tried jython/java apps http://code.google.com/p/mintty/
  * pay someone to add CJK support to the version of Jython you are using
  * add CJK support yourself to the version of Jython you are using
