[Jython-users] No UnicodeError exception?

[Patrick S. <Pat...@qu...>]

In trying to figure out how to get an XML document containing unicode
characters correctly serialized to an output file, discovered that Jython=
 and
Python behave differently when attempting to write Unicode characters to
files.  Is this a known issue?  (Not that it actually helps solve my orig=
inal
problem, but hey...)
