unicode revisted

[June Kim]

I posted something similar to this a few weeks ago but
got no response from anyone. Maybe we have very few
people interested in the internationalization.

My question is,

Supposing sys.getdefaultencoding() == 'whatever'
What is u'abracadabra' == unicode('abracadabra') == 
unicode('abracadabra','whatever') ?

Aren't they supposed to be the same semantically, and effectively?


Thanks in advance

June
