Re: [Pyobjc-dev] NSError.localizedDescription() and Application Bundles

[James R E. <Jam...@lr...>]

Hi Jean-Pierre,

The problem you're having is actually at the print statement at the  
very end.  The problem is that your sys.stdout.defaultencoding is  
usually set to US-ASCII rather than UTF8.  Unfortunately, the pythonic  
way of changing this encoding is via the site-config file, which you  
can't very well distribute with your python application.  You can  
either restrict yourself to NSLog, which does properly output UTF-8  
encoded unicode text, or you can manually encode your output via:

	print error.localizedDescription().encode('utf8')

This approach is better suited if you can bury that deep inside your  
own logging-like mechanism, since you don't want a single missed  
".encode('utf8')" to introduce a unicode bug to your code.

If anyone has any alternative suggestions, btw, I'd love to hear  
them.  Unicode in python is often a source of headaches.

Cheers!
James
