Thanks Ming, this is helpful.

Ah, it seems that in c’’8 8 the 8 does not have a pitch property when it is 
received by the jianpuMusic function:

\displayMusic shows that c’’8 becomes:

(make-music
'NoteEvent
'duration
(ly:make-duration 3)
'pitch
(ly:make-pitch 1 0))

…and then 8 becomes

(make-music
'NoteEvent
'duration
(ly:make-duration 3))

with no pitch property.  So I’ll need to handle these pitch-less note events. 

> Lyric treat -  0  as notes

Yes, this I knew about, but I don’t know what the solution might be.  The - and 
0 are notes with modified stencils, which gives us good spacing and lets 0s 
have beams.  But that breaks how the lyrics align with the notes, and I can’t 
think of an automatic way to adjust the lyric durations so that, for example, a 
syllable that originally aligned with a whole note now aligns with four quarter 
notes.  

So currently you have to do this by hand by adjusting the durations of lyrics 
or adding skips, etc.  You could use tags, skips, and removeWithTag to have one 
set of lyrics that works with either standard notation or jianpu.
