Um. Ok. That tells us that the font designer was slightly inefficient. That's not going to cause any rendering problems.

So it seems that *easy fix* would be to check in PfaEdit during export wether
some lines are represented with curves, and replace them with vector.
PfaEdit does check whether curves can be replaced by lines. Its check is mathematically precise.

It is also an irrelevant fix.

I have looked at the copies of Nimbus Sans I have on my machine and there is no curve in B where there should be a line. In the examples you gave all I see are a bunch of hlineto operators.
