If not then you should follow *exactly* the approach in pretty and you should be on the safe side. I see that you implemented printers for physics module outside sympy.printing. What it the rationale for this? I would create mixin classes for repr, str, pretty and latex with appropriate printing methods and add those classes as basses to appropriate printers. This way, you will have to make sure that Unicode is setup properly only in one or two files, not n >> 2. I would also use U() function from pretty_symbology.py, to make sure that Unicode character you use is actually globally available. U() will give you None if given character (which you will specify by Unicode name) belongs to the standard or not. It often happens that on a certain platform you can get more Unicode symbols, but they aren't available elsewhere. > > Regards > Stefan > > P.S. # -*- encoding: utf-8 -*- was present when the tests failed > > -- > You received this message because you are subscribed to the Google Groups > "sympy" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]. > For more options, visit this group at > http://groups.google.com/group/sympy?hl=en. > Mateusz -- You received this message because you are subscribed to the Google Groups "sympy" group.
