dvipdfmx:warning: Invalid CMap

[Shunsaku Hirata]

Hi Jean-François,

I identified the cause of this problem.
There should be no problem in output PDF but dvipdfmx wrongly issues
a warning.

Problem description:
Dvipdfmx is unnecessarily trying to create an empty ToUnicode CMap,
and as a result, it wrongly issues a warning.

It will be fixed soon.

Thanks,
Shunsaku Hirata
