[XML-SIG] printing Unicode xml to StringIO (original) (raw)

I'm using xml.dom.ext.Print() to print a dom node to a StringIO object, which fails when the data cannot be interpreted as ASCII. After a lot of XML hacking, I think it is not in the XML code, but in the StringIO:

Python 2.2+ (#4, Dec 27 2001, 12:46:04) [GCC 2.96 20000731 (Red Hat Linux 7.1 2.96-81)] on linux2 Type "help", "copyright", "credits" or "license" for more information.

import StringIO s=StringIO.StringIO() u=u'\xc9' s.write(u) Traceback (most recent call last): File "", line 1, in ? File "/usr/local/lib/python2.2/StringIO.py", line 139, in write s = str(s) UnicodeError: ASCII encoding error: ordinal not in range(128)

What is going wrong here? According to the manual, StringIO should be able to handle utf-8 strings... Also note that the different versions of python on my system all seem to behave differently on the code above. For example, in 2.1, the write succeeds but the latin-1 encode seems to go wrong:

Python 2.1.1 (#1, Aug 13 2001, 19:37:40) [GCC 2.96 20000731 (Red Hat Linux 7.1 2.96-96)] on linux2 Type "copyright", "credits" or "license" for more information.

import StringIO s=StringIO.StringIO() u=u'\xc9' s.write(u) s.getvalue().encode('latin-1')" # Expected '�' here: '\xc9' s.getvalue() # Still it claims to be unicode: u'\xc9'

Any help would be appreciated,
