Are you sure it is a good idea to give it a public name?  I have no
problem with calling it _PyUnicode_ConvertToASCIIDecimal().
("Transform" may be a better term, though.)

Yes, that was a bad idea, but the old EncodeDecimal was replacing all
Unicode space with ASCII ' '.  It will be hard to replicate old
behavior without doing the same in  ConvertToASCIIDecimal().

OK.  I had the same reservations about recommending private API.

Will do.  I should also add some more tests for error conditions.  I
test for leaks, but if the error branch is not covered, it is not
covered.
