Bug Description

At 11 PPEM with manual hinting enabled, the width of the bowl in the lowercase letter "g" is 1 pixel wider than it should be compared the bowl in lowercase letters like "o" (Or conversely the 'o' is one pixel too narrow!)

I am using it at font size 8 on konsole (11 PPEM).

Proposed solution:
  1. Hint the 'o' bowl 1 pixel wider
  2. Hint the 'g' bowl 1 pixel narrower
  3. Confirm consistency across the whole character set

Thaddee: Thank you for the report. Please can you post a screenshot showing exactly what you're seeing, in context that you're seeing it.

Please could you please also copy and paste the two special debugging characters U+EFFD and U+F000 ('' and '') into the terminal or editor before taking the screenshot.

There it goes, in the word "gogo".
The debug sequence is in the first line, in the id.

Thank you for screenshot which shows 11 PPEM (6x11 rendering cells). My guess is the that it needs some global/CVT code so that the bowl width decision for a/e/b/d/g/o/p/q/u is visually consistent (whether that reduces the width of the 'g', or increases the width of the 'o'.
