Comment 7 for bug 713950

Discussions may continue only about why your proposed appearance on how the fonts are displayed would be better than the current one and fit for the majority of people.

Any reasons about "it will avoid applications which don't support fallback" should just stop: go and fix the buggy applications. For example if you like to fix a related PDF rendering issue, please go to Bug #659280 and put your efforts on pushing/fixing poppler(-data).
