Just to be clear here -- is PDF specifically bytes+ascii?
Or could there be some-other-encoding unicode in there?
If so, then you really have a mess!
if it is bytes+ascii, then it seems you could use a unicode object and
encode/decode to latin-1
Perhaps still a bit klunkier than formatting directly into a bytes object,
but workable.

Let's see, I think that would be:
u'%.1f %.1f %.1f RG' % (r, g, b)
then when you want to write it out:
.encode('latin-1')
dumping the binary data in would be a bit uglier, for teh image example:
stream
...binary image data...
endstream
endobj
u"stream\n%s\nendstream\nendobj"%binary_data.decode('latin-1')
I think.....
not too bad, though if nothing else an alias for latin-1 that made it clear
it worked for this would be nice.
maybe ascii_plus_binary or something?
