Dear John,

Okay, I think that I have solved the issue. The clue was in 
https://hackage.haskell.org/package/texmath-0.8.6.5/changelog where it 
states "Fixed overbrace, underbrace (#82). Previously we were using the 
wrong character: U+FE37 instead of U+23DE. This didn't work in Word." If I 
switch the unicode character in the input mathML then the conversion does 
then work correctly in a simple test. 

The mathML does still render correctly so I guess I need to switch unicode 
under and over braces. 

Sorry for the confusion and thanks for your time.
Emma
