locale.CODESET / different in python shell and scripts

[Nuff Said]

When I type the following code in the interactive python shell,
I get 'UTF-8'; but if I put the code into a Python script and
run the script - in the same terminal on my Linux box in which
I opened the python shell before -, I get 'ANSI_X3.4-1968'.

How does that come?

Thanks in advance for your answers! Nuff.


The Code:

  import locale
  print locale.nl_langinfo(locale.CODESET)
