Odd message during doc build

[James Lowe]

Hello,

I say 'odd' it's that while I don't sit and stare at the terminal while it 
compiles the doc (well sometimes I do) I have not noticed this message - that 
fills up the screen for a minute before carrying on as normal

Error: Illegal entry in bfrange block in ToUnicode CMap
Error: Illegal entry in bfrange block in ToUnicode CMap

etc.

I have pulled, done a make;  touch Doc/notation.tely ; make doc

and saw this fly by the screen. I only noticed it because there is never a set 
of messages that just sits whizzing past in this quantity.

Otherwise it seems to be happily chugging along.
