Hi,
Probing my system from Python 2.3.4 gives import locale, sys locale.getdefau ltlocale()
('fi_FI', 'cp1252') locale.getprefe rredencoding()
'cp1252' sys.getdefaulte ncoding()
'iso-8859-1'
Manual says:
locale.getprefe rredencoding():
Return the encoding used for text data, according to user preferences...
sys.getdefaulte ncoding()
Return the name of the current default string encoding
used by the Unicode implementation
When should I use locale.getprefe rredencoding() and when
sys.getdefaulte ncoding()?
Why two different encodings 'cp1252' and 'iso-8859-1' are provided
for my Windows 2000 system?

This is already troublesome; it means somebody (perhaps you)
has tampered with your Python installation. The default system
encoding is ascii, and it should not be changed unless
absolutely necessary.
When should I use locale.getprefe rredencoding() and when sys.getdefaulte ncoding()?
There should never be a need to probe sys.getdefaulte ncoding(),
as it should always be ascii.
locale.getprefe rredencoding() should be used when converting
Unicode strings to and from byte strings to be stored on the local
system (e.g. in files). Notice that this may or may not be adequate
also when printing data to the terminal. Specifically, on Windows,
the terminal often uses yet another encoding.
Why two different encodings 'cp1252' and 'iso-8859-1' are provided for my Windows 2000 system?
Python provides many more encodings, including UTF-8, KOI-8R,
ISO-8859-2, cp1250, and so on. Having many codecs available in
the library is a good thing, because different applications have
different needs.
I somehow feel this doesn't answer your question, but then, I don't
fully understand the question.

Martin

I do not recall changing it manually so just in case I reinstalled
latest versions of my default set of python tools in this order:
Python-2.3.4.exe
pywin32-203.win32-py2.3.exe
wxPython2.5-win32-unicode-2.5.3.1-py23.exe
ctypes-0.9.2.win32-py2.3.exe
numarray-1.1.win32-py2.3.exe
pychecker-0.8.14
and now it IS "ascii". When should I use locale.getprefe rredencoding() and when sys.getdefaulte ncoding()?

Can I find out the terminal encoding somehow? Why two different encodings 'cp1252' and 'iso-8859-1' are provided for my Windows 2000 system?

The reason I asked was that since my Window's regional settings
matches "cp1252" I was puzzled by sys.getdefaulte ncoding()
not being the same.

I have a program. It takes in files that are delimited.
The delimiters are declared in the file by looking at
fixed positions in the file (If you work with ANSI x12
files, you know what I mean). This normally isn't a
problem, but I'm getting a file that is using some odd
characters as delimiters.
Specifically, a Hex 'BA' is declared as a delimiter. I

to convert back and forth. But why isn't Unicode considered a regular

Hi group,
I could use a bit of guidance on the following matter.
I am starting a new project now and must make some decisions regarding

Environment: PHP4.3, Postgres7.4.3
I must be able to receive forminformation and store that in a database and
later produce it on screen on the client (just plain HTML).
