[Pythoncard-users] Unicode [slightly OT]

[Alex T. <al...@tw...>]

If I start up the Python interpreter (i.e. open a DOS shell box, and 
type "python") I get my Python interpreter. I then type in the following 
two lines, and get an error :

> C:\Documents and Settings\Eleane>python
> Python 2.4.1 (#65, Mar 30 2005, 09:13:57) [MSC v.1310 32 bit (Intel)] 
> on win32
> Type "help", "copyright", "credits" or "license" for more information.
> >>> s = u'a\u2019s'
> >>> print s
> Traceback (most recent call last):
>   File "<stdin>", line 1, in ?
>   File "C:\Python24\lib\encodings\cp850.py", line 18, in encode
>     return codecs.charmap_encode(input,errors,encoding_map)
> UnicodeEncodeError: 'charmap' codec can't encode character u'\u2019' 
> in position
>  1: character maps to <undefined>
> >>>

If instead I start the PythonCard codeEditor, and start a Shell (F5), 
and type the same two lines, it works properly.

I tried the basic python interpreter adding the imports that are visible 
within the codeEditor shell, but still get the same problem.

Anyone got any clues ?
Does the code editor do something non-obvious that makes this all work 
right when it opens a shell ?
Or is there something additional I could try ?

[I don't really care about what the code editor does - just about being 
able to get my app working, perhaps by doing the same as the codeEditor.]

(for now, I'm working around it by doing
   s = s.encode('ascii', 'replace')
which simply replaces all the odd characters by '?'s - ok for the short 
term, but I do need to figure out a better answer).
