Description Filipe Saraiva 2013-09-01 21:20:03 CEST

Hello, I am getting a UnicodeDecodeError after try import pylab and pyplot, from matplotlib, in python2. My keyboard is pt-br but I do not type any special character during the import.

The console output follow below:

is the fix ok ?

Comment 5 Filipe Saraiva 2013-09-11 20:55:36 CEST

Yes, it is ok! Thank you!
I am having a problem with matplotlib now but it is related with upstream, not with Mageia.
