How to print this character u'\u20ac' to DOS terminal
Who could explain the follow issue ?
>>> print u' '
>>> print u''
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'gbk' codec can't encode character u'\x80' in
position 0: il
legal multibyte sequence
or I just put the unicode number
>>> print u'\u0394'
>>> print u'\u20ac'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'gbk' codec can't encode character u'\u20ac' in
position 0:
illegal multibyte sequence
My terminal is cmd.exe under windows XP.
what's the different between the two character ? what can I do if I
want to print the u'\u20ac'?

see http://zh.wikipedia.org/wiki/GBK for details on GBK.
It seems that GBK (or, rather, code page 936) supports the delta
character, but not the euro sign.
To change that, you can use "chcp" in your terminal window.
For example, if you do "chcp 850", you should be able to
display the euro sign (but will simultaneously use the ability
to display the letter delta, and the chinese letters).
I don't know whether the terminal supports an UTF-8 code
page; you can try setting the terminal's code page to
65001 (which should be UTF-8).

I find that the u'\u20ac' related 'mbcs' encode is 0x80, I could print

But the string contained the u'\u20ac' is get from remote host. Is
there any method to decode it to the local 'mbcs'?

remote_string = u'\u20ac'
try:
local_string = remote_string.encode('mbcs')
except:
# no mbcs equivalent available
print "encoding error"
else:
# local_string is now an 8-bit string
print "result:", local_string
# if console is not mbcs, you should see incorrect result
assert result == '\x80'
Mbcs is windows-only so I couldn't test this.
If your application handles text, it may be easier to just leave everything
in Unicode and encode to utf-8 for storage?

But I doubt this way may not work on linux. Maybe I should write some
additional code for supporting both windows and linux OS.

Depends on what you want to do. Printing to a DOS terminal is hard in
Linux :-) If you write server code, best to keep all text in unicode.
