I'd like to correct a misapprehension here: RTF files are not a "binary
format" in the usual sense of that phrase - there are no non-ASCII
characters, newlines are handled normally, etc.  They're text files, but
with lots of funky formatting codes included - which are themselves all
text.  They're a lot like badly-formatted, insanely complicated XML,
actually.

They're full of gibberish-looking strings like the above, and the nesting of
curly braces can run to dozens of layers deep - however, if you want to get
a quick idea of what's going on in an RTF, the fastest way is to unfold it
(search-and-replace each "{" and "}" with "{\n" and "}\n" respectively) and
indent each opened curly brace.  Then if you want to give yourself a
headache, you can sit down with Microsoft's RTF specification and figure out
what all those codes do.
