Thank you for the link. I am using Notepad, which inserts the byte order
mark. Following the links a bit further, I gather that the version of
Notepad that I am using may not identify a UTF8 file correctly if the
byte order mark is omitted. Also, as I mentioned, Python makes use of
it. (From the Python documentation on Encoding declarations: "If the
first bytes of the file are the UTF-8 byte-order mark ('\xef\xbb\xbf'),
the declared file encoding is UTF-8 (this is supported, among others, by
Microsoft’s Notepad).")
The conclusion seems to be that I must use one editor for Python, and
another for Postgres.
The problem is Notepad has a limited view of the text world. If you use
it only in the Microsoft universe and for simple tasks it is sufficient.
The issues arise when you try to work with files outside that scope. For
long term peace of mind you will better served by more capable text
editors(see other posts for suggestions). As to the Python
documentation, it goes on to say:
http://docs.python.org/tutorial/interpreter.html#source-code-encoding
"Notice that this signature is not understood in older Python releases
(2.2 and earlier), and also not understood by the operating system for
script files with #! lines (only used on Unix systems)."
From the Zen of Python:
"Explicit is better than implicit"
Following that the preferred way of declaring an encoding would be:
# -*- coding: utf-8 -*-
