I've resolved it by overriding the str method in my own objects, and making "x.encode('utf-8')" inside it, where x is a property inside the object. But, if I receive a third-party object, and I make "str(object)", and this object has a non-ASCI...

XML specification lists a bunch of Unicode characters that are either illegal or "discouraged". Now, given a string, what is the best way to remove all those illegal chars from it? Right now, my best bet is a regular expression, but it's a bit of a mouthful: illegal_xml_re = re.compile(u'[\x00-\x08\x0b-\x1f\x7f-\x84\x86-\x9f\ud800-\udf...
