Yes, I basically followed g_object_set doing init_property_value() and
gperl_value_from_sv() once I realized value_validate isn't a general
validity check, only further restrictions on a GValue of already correct
GType.

Maybe, but I think value_validate and value_cmp will be working on
things that you're soon to pass to or from get_property and
set_property, so I think they might best follow those latter, for better
or worse.

I guess the blame lies with GValue unhelpfully not distinguishing a
unichar.  I suspect trying to fight against that in unichar paramspecs
might only lead to more pain, or only pain of a different kind. :-)

The best I can think is just try to confine the numeric style to things
related to parameters and paramspecs and put it down to hysterical
raisins. :-(

I'll try to do that at least for multiple files.
