Heh.  Good idea, thanks, tried that.  Then tried it again, piping the result 
to a hex editor, since the diff output didn't seem (on screen) to show any 
differences!  The differences become clear in hex.

What has happened is that the original Javascript, in cleaning up character 
input, is replacing certain non-standard characters with standard 
equivalents, using a regexp replace.  Quanta (as presumably Kate) drops these 
characters from the regexp when writing the file, presumably leading to the 
Javascript not parsing correctly (as far as IE is concerned: I'm not sure 
what Firefox has actually made of the 'amended' regexp!).

Can this be sorted out by using a different character set?  The chartacters in 
question lie in the range 0x91 to 0x96, and appear to be characters used by 
MS Word for things like a long dash and open/close quotes.
