UnicodeDecodeError: 'ascii' codec inside controller

[Carlos Alberto Costa Beppler]

I´m having an very strange UnicodeDecodeError on the following program. 

The most strange is that before start the application the same formatting instruction works, it raises the error only inside the GET (or any other controller method).

The test program is:

==============================

#!/usr/bin/python

# -*- coding: utf-8 -*-

import os

import sys

import web

class Index(object):

    def GET(self, id = None):

        if id:

         # this raises UnicodeDecodeError

         msg = 'Não encontrado: %s' % web.ctx.path

         raise web.notfound(msg)

        return 'Encontrei'

urls = (

    '/(.*)', 'Index'

)

application = web.application(urls, globals())

# this works

msg = 'Não encontrado: %s' % '/test'

web.debug(msg)

if __name__=='__main__':

    application.run()

==============================

The log message generated on server is:

==============================

beppler@squeeze:~/site$ python test.py

'N\xc3\xa3o encontrado: /test'

http://0.0.0.0:8080/

'N\xc3\xa3o encontrado: /test'

    return tocall(*args)

    msg = 'Não encontrado: %s' % web.ctx.path

Have you tried marking your string as unicode?

msg = u'Não encontrado: %s' % web.ctx.path

[Carlos Alberto Costa Beppler]

Thanks.

It worked.

I understand that this exception happening because of the web.ctx.path is an unicode string and the % operator is converting the "format" string to unicode using the defatult encode. Is this right?
