file.write() of non-ASCII characters differs in Interpreted Python than in script run

Maybe, I can explain the behavior: the interactive interpreter uses magic
to determine the console's encoding and automatically uses this
for console output. No such magic in non-interactive interpreter use.
Therefore, you can get "UnicodeEncoding" problems in non-interactive use
which you do not see in interactive use.
