I don't expect it to be easy to change the terminal encoding. There is
really no reason to do it. UTF-8 is so ubiquitous…
The best solution to your problem depends on why you need to change
the character encoding of the terminal.
I expect both the python engine and the curse library to read UTF-8 files
just fine and do it even better than CP437 if UTF-8 is the system encoding.
If they don't, they are probably not correctly configured or compiled. You
should be able to write and test your script using UTF-8.
If you really need to write your script using CP437, there are a number of
text editors that can read and write files using whatever encoding you
want. Vim and kwrite can both do it. There is no need to change the
terminal encoding just to write a script with CP437.
If you need to send the script to someone that specifically requested
CP437 encoded files, you should write and test the script using UTF-8
(taking care of only using characters available in CP437) and then, when
you are ready to give it away, convert it using iconv:
iconv -f utf8 -t cp437 source -o source_in_cp437
Note that there are a number of text editors on Windows that can read
UTF-8 files if that's your concern.
Similarly, if your python script must produce CP437 output, you can convert
the output on the fly using iconv
python script | iconv -f utf8 -t cp437 | other_command
That's admittedly not very convenient. So, does the python "encode"
command (http://www.tutorialspoint.com/python/string_encode.htm) help
you?
