Comment 47 for bug 791076

I ran the script over all the .ttf files in /usr/share/fonts/truetype/ubuntu-font-family, and replaced them all with the 'fixed' versions. Most of the on-screen fonts looked horrible (this included the greeter fonts, menus, and various dialogs). However, it did kind of fix the Emacs bug.

Then I restored all of the original (i.e. "unfixed") fonts except UbuntuBetaMono-BI.ttf (the original troublemaker). This fixed all the system fonts, and also allowed the Emacs default font to work properly. The only problem I found then was that all italic-regular fonts in Emacs were rendered as italic-bold.
