You changed the Writer.write to StringBuffer operations. I'd say
that appending to a StringBuffer is much slower than writing

Really? Well, I have to admit, this was a late-night idea :-/
And I didn't read the TechTips for a long time:
So String vs. StringBuffer is 1:1/6 (StringBuffer.append is six
times faster or needs only a sixth than concatenating Strings). And
StringBuffer.append->Writer vs. String->BufferedWriter is not
mentioned that explicitly anywhere, but if both are StringBuffer-
techniques, this is only two times slower. As said before, RTF is
quite fast, no layout managing, that sort of thing. So not that bad
You're quite right, I believe. Any changes to this will lead to a
marginal overall improvement at best.
This whole thing got me wondering, though, if there are any other
places in the rtf-lib where characters outside of the 7-bit ASCII
range are incorrectly written to the output as characters (instead of
passing through RtfStringConverter to do unicode escapes).
We'll keep looking as well.
Thanks for your input/feedback!
