UTF-8 is usually a good choice. Then open it with codecs.open() instead of the built-in open(): import codecs f = codecs.open(filename, "w", "UTF-8") f.write(u"\nentry." + node.tagName + u" = " + cValue) Peter -- http://mail.python.org/mailman/listinfo/python-list

There are two operations:
1. Concatenating the strings.
2. Invoking write().
First step I would make is to find out which of the two is raising the
exception. Anyway, it probably is the second one, i.e. the call to write().
What is happening there is that the file's codec is trying to convert the
Unicode string to bytes for the configured encoding ('ascii') but fails
because there is no representation for u'\x93' there (Note: ASCII only uses
the byte values from 0 to 126, the above is 147).
The remedy is to set the output encoding to e.g. UTF-8 (default for XML) or
ISO8859-1 (default for HTML) or whichever encoding you want. Otherwise,
just throw the error message at the search engine of your least distrust to
find a bazillion of other users that had similar problems. ;)

Please don't confuse utf-8 with unicode. The former is an encoding of the
latter. Which is a crucial difference, as something being encoded (either
in utf-8 or any other encoding) needs to be *decoded* before being dealt
with in python as unicode-object.
Which is what's causing your troubles here. cValue is a *byte*string
containing some non-ascii-characters.
If you are sure cValue is utf-8-encoded, you can do
u" = " + cValue.decode("utf-8")
to remedy the problem.

Trying to write a string to a file.
self.dataUpdate.write(u"\nentry."+node.tagName+ u" = " + cValue)
cValue contains a unicode character. node.tagName is also a unicode string
though it has no special characters in it.
So what's the encoding of your file?
If you didn't open dataUpdate with codecs.open, and you don't encode the
string someway - i.e. text.encode('utf-8') python has no way to know it.

Unicode in writing to a file
Py 2.5 Trying to write a string to a file. self.dataUpdate.write(u"\nentry."+node.tagName+ u" = " + cValue) cValue contains a unicode character. node.tagName is also a unicode string though it has no special characters in it. Getting the error: UnicodeEncodeError: 'ascii' codec can't encode character u'\x93' in position 22: ordinal not in range(128) Thanks. -- http://mail.python.org/mailman/listinfo/python-list
