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!
