Bug Description

Rendered in 23pt Regular

Sample Glyphs:

When a couple of guys. Who were up to no good.


I encountered this on a Launchpad Answers Site: The capital W of the question was extremely unsymmetrical. I don't mean metrically unsymetrical. I mean optically. Do you perceive this as a problem, too?

BTW: What does this 31 mean? Is it the size in ppem?

Yup, definitely obvious in the screenshot because all the diagonal stems end up at different angles.

summary: - Hinting: capital W not symetrical in 23pt regular
+ Hinting: capital 'W' not symmetrical at 31 ppem (23pt regular)

adoa: yes, the 31 is the pixels-per-em, and the PPEM is what determines the hinting set used.

scope of the Ubuntu Font Family includes all the languages used
by the various Ubuntu users around the world in tune with
