The script below uploads files to a web server. Currently it
overwrites a file if it already exists. I'm instead trying to rename
the old file with an appended date/timestamp before the new file is
uploaded. I *think* I have the idea down but it's not be implemented
in the script correctly. Any hin
Instead, use a compatible character encoding. Note the explicit conversion.
fh.write(line.encode('utf-8'))
Alternatively, you can write sixteen bit unicode directly to a file:
import codecs
f = codecs.open('unicodetest.txt', mode='w', encoding='utf-16&

red in your database, and
you should be able to use it in Delphi too I believe? Its been years since I
used delphi, but. At the point where there's a barrier between 'your' stuff
and 'other stuff', you convert from unicode into an encoding-- if you must.
