Here's an output stream encoder I have used. It might be kind of screwball,
so I'd welcome any feedback on it, but it does work for encoding output
streams.
import sys
class OutStreamEncoder(object):
"""Wraps an out stream with an encoder"""
def __init__(self, outstream, encoding=None):
self.stdout = outstream
if not encoding:
self.encoding = sys.getfilesystemencoding()
else:
self.encoding = encoding
def write(self, obj):
"""Wraps the output stream's write method, encoding it with
the specified encoding"""
self.stdout.write(obj.encode(self.encoding))
def __getattr__(self, attr):
"""Delegate everything but write to the stream"""
if attr != "write":
return getattr(self.stdout, attr)
return self.write
>>> from cStringIO import StringIO as si
>>> out = si()
>>> nihongo = unicode("日本語", "sjis")
>>> print >> out, nihongo
Traceback (most recent call last):
File "<pyshell#40>", line 1, in <module>
print >> out, nihongo
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-2:
ordinal not in range(128)
>>> out = OutStreamEncoder(out, "utf-8")
>>> print >> out, nihongo
>>> val = out.getvalue()
>>> print val.decode("utf-8")
日本語
