DeprecationWarning: Non-ASCII character '\xc0'

P: n/a
Hello All,

I have this file and when I import the file in the python interpretor
I get the following error:

"__main__:1: DeprecationWarning: Non-ASCII character '\xc0' in file
trans.py on line 11, but no encoding declared; see
http://www.python.org/peps/pep-0263.html for details"

I am not sure what encoding to use. I am not sure where to look. I
picked one out of the documentation. Here is what I used:
# -*- coding: utf-8 -*-

Questions:
1) Is there a list I can pick the encoding from?
2) How can I find more about encoding?

Thanks, Ahsan

Looks like the data you posted was encoded as iso-8859-1 (aka, latin-1), so
I suggest you use:

# -*- coding: iso-8859-1 -*-

as your coding comment.

ahsan> Questions:
ahsan> 1) Is there a list I can pick the encoding from?

Look at the filenames in the encodings package (part of the standard
distribution).

ahsan> 2) How can I find more about encoding?

Pick and choose from the results in found in these googlings:

http://www.google.com/search?q=encod...www.python.org
http://www.google.com/search?q=unico...www.python.org

I recommend you avoid using non-ASCII characters in source code in
this specific case.
'À':'A', '<\\\#203>':'A', '&Agrave;':'A', '':'A',


Here, is a non-ASCII character. If you copy-and-past this
to a Python session, and do
ord("")

192

you find that it really is the character with the byte value
192. So reformulate the line above to

'À':'A', '<\\\#203>':'A', '&Agrave;':'A', chr(192):'A',

If you change all lines in this respect, you won't need an
encoding declaration anymore, as your source code is plain ASCII.

Regards,
Martin
