I agree.

Undotted I get right the squared breve as I expect --- if there is nothing
dotted around.

Yes, I saw something similar. That's why I asked. And if I remember right,
there was also a problem in counting lengths in the pmx input when using
dotted breves. But the problem was not that straight forward. I didn't
isolate that really and I don't have the example at hand now.

Here is the example. I tried to go around the problem using something like
"\pt N\breve N\ rb9d" instead of "g9d". But this causes a "Bad error in
fnote"
