问题
Hello i was wondering if you know any other way to encode a string to a url-safe, because urllib.quote is doing it wrong, the output is different than expected:
If i try
urllib.quote('á')
i get
'%C3%A1'
But thats not the correct output, it should be %E1
As demostrated by the tool provided here this site
And this is not me being difficult, the incorrect output of quote is preventing the browser to found resources, if i try
urllib.quote('\images\á\some file.jpg')
And then i try with the javascript tool i mentioned i get this strings respectively
%5Cimages%5C%C3%A1%5Csome%20file.jpg
%5Cimages%5C%E1%5Csome%20file.jpg
Note how is almost the same but the url provided by quote doesn't work and the other one it does. I tried messing with encode('utf-8) on the string provided to quote but it does not make a difference. I tried with other spanish words with accents and the ñ they all are differently represented.
Is this a python bug? Do you know some module that get this right?

According to RFC 3986, %C3%A1 is correct. Characters are supposed to be converted to an octet stream using UTF-8 before the octet stream is percent-encoded. The site you link is out of date.
See Why does the encoding's of a URL and the query string part differ? for more detail on the history of handling non-ASCII characters in URLs.

Ok, got it, i have to encode to iso-8859-1 like this
word = u'á'
word = word.encode('iso-8859-1')
print word

Python is interpreted in ASCII by default, so even though your file may be encoded differently, your UTF-8 char is interpereted as two ASCII chars.
Try putting a comment as the first of second line of your code like this to match the file encoding, and you might need to use u'á' also.
# coding: utf-8

What about using unicode strings and the numeric representation (ord) of the char?
>>> print '%{0:X}'.format(ord(u'á'))
%E1

In this question it seems some guy wrote a pretty large function to convert to ascii urls, thats what i need. But i was hoping there was some encoding tool in the std lib for the job.
