It looks like upstream is dead-set against fixing the issue for
toolchains without wchar. I think it is simpler to just add a dependency
to wchar. The only user of qpdf, cups-filters, already depends on wchar
anyway.
I'll do so and push to master.
(Note that I commented on your upstream PR at the same time you did,
with roughly the same arguments! ;-) )
Regards,
Yann E. MORIN.
