Well, in luatex tries to be 100% compatible with XeTeX (where
applicable) and in this case it clearly wasn't, so that qualifies
as a bug.



Oh OK, thanks that's useful information. So if I get more reports of packages doing different things on the two engines I'll go that route.


As was the missing \Umathcharnumdef that I added this
morning btw.

Yes thanks to all for that quick patch.


Given that bm has been completely stable for 20 years, it's not that big
a deal to have to update it for the unicode age, but it would be good
(for bm, and for every other math package author) if that only needs to
be done once. My main concern was that was not the case. But actually if
I understand the replies correctly I should be able to share the code
for xelatex and lualatex so long as I avoid \mathcode once I have
detected either of them?

I think so,

I'll give it a try later.

but I have no knowledge of the internals of bm.

I'd advise staying in that state:-)

Best wishes,
Taco
