Here you are right. I was (without knowing it) doeing the wrong thing.
Well, my judgement was based on a confusion that I haven't been able to clear so
At first my file was encoded differently than the python default encoding and I
coded even a different encoding in the file head. After I'd adaped all this
correctly my code worked well.
I tried to use the same code interactively on the IPython shell. As I said from
my previous post, the shell uses again a different encoding. Therefore, the same
code that worked well from file did fail. When I found out that I could set the
default encoding to UTF-8 you warned me of a lesser portability.
I am totally lost:
* python has ascii as default encoding
* my linux uses UTF-8 (therefore all files created on linux are UTF-8)
* windows uses cp1250
* IPtyhon something else: on the machine where I am currently on stdin is set to
So what encoding to I use to display and process characters that exeeed the
standard english alphabet?

My initial question was:
1) get a coordinate (DEG° MIN' SEC'') as input from user via easygui
2) split that string into its subscripts: degrees, minutes and secons
3) do some processing of the 3 varaibles
4) print the output with easygui.
I am not really interested which is the best encoding. I want to know:
* how I do this that I don't get a encoding error?
* how do I code it that the code runs on linux and windows
from file and in IPython
Thanks again for your support. I don't want any misunderstandings. You were a
good tutor to me and are helping
patiently many user stepping into python.
