and in weberror\evalexception.py , I found this:

    def source_code(self, req):
        location = req.params['location']  # when use print, I find location is a unicode obj
        module_name, lineno = location.split(':', 1)
        module = sys.modules.get(module_name)
        if module is None:
            # Something weird indeed
            res = Response(content_type='text/html', charset='utf8')
            res.body = 'The module %s does not have an entry in sys.modules' % module_name
            return res
 

in python we know "foo%sfoo" % u"bar" gives a unicode obj,
so maybe we need a location = srt(req.params['location']) ?

I'll accept a PR to fix this issue.
