Incorrect font weight in Prince 14

davidronk
Running Prince 14.1 on Ubuntu 16 using the sample.html file below yields a pdf that uses Helvetica Bold instead of the specified Helvetica Normal. We haven't modified fonts.css.
The same sample.html file yields a pdf (correctly) using Helvetica Normal with Prince 13.5 on the same machine.
Also the pdf generates correctly on MacOS using Prince 14 and 13

Debug logging shows:

That looks normal so far, would you be able to tar up those three .ttf files and email them to me (mikeday@yeslogic.com) so we can try reproducing the problem locally?

This turned out to be an issue with one of the fonts, where Helvetica Bold had a weightClass of 400 (normal).

We have added a warning for this situation to Prince 14.2.
