Chinese and Japanese character support in python

Question

How to read correctly japanese and chinese characters. I'm using python 2.5. Output is displayed as "E:Test?????????"

path = r"E:Testは最高のプログラマ"
t = path.encode()
print t
u = path.decode()
print u
t = path.encode("utf-8")
print t
t = path.decode("utf-8")
print t

Please do read the Python Unicode HOWTO; it explains how to process and include non-ASCII text in your Python code.

If you want to include Japanese text literals in your code, you have several options:

• Use unicode literals (create unicode objects instead of byte strings), but any non-ascii codepoint is represented by a unicode escape character. They take the form of uabcd, so a backslash, a u and 4 hexadecimal digits:

  ru = u'u30EB'
  

  would be one character, the katakana 'ru' codepoint ('ル').

• Use unicode literals, but include the characters in some form of encoding. Your text editor will save files in a given encoding (say, UTF-16); you need to declare that encoding at the top of the source file:

  # encoding: utf-16
  
  ru = u'ル'
  

  where 'ル' is included without using an escape. The default encoding for Python 2 files is ASCII, so by declaring an encoding you make it possible to use Japanese directly.

• Use byte string literals, ready encoded. Encode the codepoints by some other means and include them in your byte string literals. If all you are going to do with them is use them in encoded form anyway, this should be fine:

  ru = 'xebx30'  # ru encoded to UTF16 little-endian
  

  I encoded 'ル' to UTF-16 little-endian because that's the default Windows NTFS filename encoding.

Next problem will be your terminal, the Windows console is notorious for not supporting many character sets out of the box. You probably want to configure it to handle UTF-8 instead. See this question for some details, but you need to run the following command in the console:

chcp 65001

to switch to UTF-8, and you may need to switch to a console font that can handle your codepoints (Lucida perhaps?).
