Comment 0 for bug 859677

To prevent clipping in Windows web browsers, the vertical metrics should be changed to be exactly the same as the maximum bounding box values across the family, and have 0 line gaps, which for the 0.80 files are:

Ubuntu
bbox ymax 988
bbox ymin -221

Ubuntu Mono
bbox ymax 835
bbox ymin -170

(LineGaps should be 0)

The reasons for this are explained in detail at http://code.google.com/p/googlefontdirectory/w/edit/VerticalMetricsRecommendations
