Can't input Unicode in Internal Console

[spyder-bot]

Spyder Version: 2.1.10
Python Version: 2.6.5
Qt Version: 4.7.2, PyQt4 (API v2) 4.8.4 on Windows

What steps will reproduce the problem?

1. Open internal console

   1. input following code into internal console:

      a=u"あ" What is the expected output? What do you see instead? exception raised:

Traceback (most recent call last):
File "C:\Python26\lib\site-packages\spyderlib\widgets\internalshell.py", line 336, in keyPressEvent
self.postprocess_keyevent(event)
File "C:\Python26\lib\site-packages\spyderlib\widgets\shell.py", line 791, in postprocess_keyevent

self.run_command(cmd)
File "C:\Python26\lib\site-packages\spyderlib\widgets\internalshell.py", line 394, in run_command
self.interpreter.stdin_write.write(cmd + '\n')
UnicodeEncodeError: 'ascii' codec can't encode character u'\u3042' in position 6: ordinal not in range(128)

Please provide any additional information below

. I debuged this for a while, and here is the result:

def run_command(self, cmd, history=True, new_prompt=True):
print repr(cmd) # << add this line

when I input a="あ", the output is: u'a = "\u3042"'
when I input b=u"あ", the output is: u'b = u"\u3042"'

to get a="あ" works, I need to change the following code in run_command:

self.interpreter.stdin_write.write(cmd.encode("utf-8") + '\n')

to get b=u"あ" works, I need to change the code to:

self.interpreter.stdin_write.write(cmd.encode("unicode_escape") + '\n')

to get both works I change the code in run_command() to:

self.interpreter.stdin_write.write(cmd.encode("utf-8") + '\n')

and then change Interpreter.push() to:

return InteractiveConsole.push(self, "#coding=utf-8\n" + line)

I don't know better method to solve this problem.

Thanks for the fix. I'll try to push it soon.

But may I ask: why do you want to have unicode on the internal console? I say it because it's a very simple console that show internal messages and lets us explore the Spyder namespace, so I don't clearly see the importance of adding unicode to it.

The internal console widget is very helpful for debugging pyqt applications. I found this unicode issue when I embed it into my developing application which use Japanese.
