Bug Description

showttf Ubuntu*.ttf | grep fontdirhint
        fontdirhint=2 left to right and neutrals
        fontdirhint=2 left to right and neutrals
        fontdirhint=2 left to right and neutrals
        fontdirhint=2 left to right and neutrals
        fontdirhint=2 left to right and neutrals

This probably wants to be zero ("0 Mixed directional glyphs")

The meaning of this bit changed between TrueType and OpenType - as today
there are much better ways to process and display mixed direction text.
The OpenType spec says "Deprecated (Set to 2)":
