You mean encoder.

Well yeah, it's supposed to be getting *characters*, not bytes.

Go around the encoder and write bytes directly to the file:
# Disclaimer: Completely untested
import codecs
raw_rtf = open("path/to/rtf.rtf", 'w')
png = open("path/to/png.png", 'r')
writer_factory = codecs.getwriter('utf-8')
encoded_rtf = writer_factory(raw_rtf)
encoded_rtf.write(u"whatever text we want") # use unicode
# ...write more text...
# flush buffers
encoded_rtf.reset()
raw_rtf.flush()
raw_rtf.write(png.read()) # write from bytes to bytes
raw_rtf.close()
#END code
I have no idea how you'd go about reading the contents of such a file
in a sensible way.
Cheers,
Chris
