[issue17089] Expat parser parses strings only when XML encoding is UTF-8

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

xmlparser.Parse() works with string data only if XML encoding is utf-8 (or 
ascii). Examples:

>>> import xml.parsers.expat
>>> parser = xml.parsers.expat.ParserCreate()
>>> content = []
>>> parser.CharacterDataHandler = content.append
>>> parser.Parse("\xb5")
1
>>> content
['µ']
>>> parser = xml.parsers.expat.ParserCreate()
>>> content = []
>>> parser.CharacterDataHandler = content.append
>>> parser.Parse("\xb5")
1
>>> content
['µ']
>>> parser = xml.parsers.expat.ParserCreate()
>>> content = []
>>> parser.CharacterDataHandler = content.append
>>> parser.Parse("\xb5")
Traceback (most recent call last):
  File "", line 1, in 
xml.parsers.expat.ExpatError: encoding specified in XML declaration is 
incorrect: line 1, column 30

This affects all other modules which works with XML: xml.sax, xml.dom.minidom, 
xml.dom.pulldom, xml.etree.ElementTree.

Here is a patch which fixes parsing string data with non-UTF-8 XML.
