URL encoding/decoding with Python
You are out of your luck with stdlib, urllib.quote doesn't work with unicode. If you are using django you can use django.utils.http.urlquote which works properly with unicode
I am trying to encode and store, and decode arguments in Python and getting lost somewhere along the way. Here are my steps:
1) I use google toolkit's gtm_stringByEscapingForURLArgument to convert an NSString properly for passing into HTTP arguments. 
2) On my server (python), I store these string arguments as something like u'1234567890-/:;()$&@".,?!\'[]{}#%^*+=_\\|~<>\u20ac\xa3\xa5\u2022.,?!\'' (note that these are the standard keys on an iphone keypad in the "123" view and the "#+=" view, the \u and \x chars in there being some monetary prefixes like pound, yen, etc)
3) I call urllib.quote(myString,'') on that stored value, presumably to %-escape them for transport to the client so the client can unpercent escape them.
The result is that I am getting an exception when I try to log the result of % escaping.  Is there some crucial step I am overlooking that needs to be applied to the stored value with the \u and \x format in order to properly convert it for sending over http?
Update: The suggestion marked as the answer below worked for me.  I am providing some updates to address the comments below to be complete, though.
The exception I received cited an issue with \u20ac. I don't know if it was a problem with that specifically, rather than the fact that it was the first unicode character in the string.
That \u20ac char is the unicode for the 'euro' symbol. I basically found I'd have issues with it unless I used the urllib2 quote method.
