hello,
As someone else already said,
"every time I think : now I understand it completely, and a few weeks
later ..."
Form the thread "how to write a unicode string to a file ?"
and my specific situation:
- reading data from Excel, Delphi and other Windows programs and unicode
Python
- using wxPython, which forces unicode
- writing to Excel and other Windows programs
almost all answers, directed to the following solution:
- in the python program, turn every string as soon as possible into unicode
- in Python all processing is done in unicode
- at the end, translate unicode into the windows specific character set
(if necessary)
The above approach seems to work nicely,
but manipulating heavily with string like objects it's a crime.
It's impossible to change all my modules from strings to unicode at once,
and it's very tempting to do it just the opposite : convert everything
into strings !
# adding unicode string and windows strings, results in an error:
my_u = u'my_u'
my_w = 'my_w' + chr ( 246 )
x = my_s + my_u
# to correctly handle the above ( in my situation), I need to write the
following code (which my code quite unreadable
my_u = u'my_u'
my_w = 'my_w' + chr ( 246 )
x = unicode ( my_s, 'windows-1252' ) + my_u
# converting to strings gives much better readable code:
my_u = u'my_u'
my_w = 'my_w' + chr ( 246 )
x = my_s + str(my_u)
until I found this website:
http://diveintopython.org/xml_processing/unicode.html
By settings the default encoding:
I now can go to unicode much more elegant and almost fully automatically:
(and I guess the writing to a file problem is also solved)
# now the manipulations of strings and unicode works OK:
my_u = u'my_u'
my_w = 'my_w' + chr ( 246 )
x = my_s + my_u
The only disadvantage is that you've to put a special named file into
the Python directory !!
So if someone knows a more elegant way to set the default codec,
I would be much obliged.
cheers,
Stef
