When you type something like 'ç' or u'ç', Python reads your source and
it's important whether it know what encoding it is in. The solution you
law in previous posts, were to declare the coding of the Python source
file, which is the right thing to do.
Just to let you know what happens here: There's something called Unicode
object. Python can create an Unicod object by _decoding_ a string. In
order to do that, assuming that your source is encoded in UTF-8, you do
like this:
unicode_obj = 'ç'.decode('utf-8')
This function returns a Unicode object, which can be later _encoded_ to
a string:
utf_8_encoded_string = unicode_obj.encode('utf-8')
Back to your example, you typed: u'ç'.encode('utf-8'), which told
Python: Take this Unicode object and encode it in UTF-8. But hey, 'ç' is
not a unicode object, it's a string! How is this string encoded? Dunno,
the source doesn't say. In such a case we assume ASCII. But hey again,
this is not an ASCII character! I'm going to complain!
I hope it helps in the future, so you know what decoding and encoding
means.
Cheers,
Maciej
