When trying to open any of the source fonts, for example LiberationMono-Bold.sfd from trunk with FontForge I receive the following error: "LiberationMono-Bold.sfd is not a known format (or is so badly corrupted as to be unreadable)".
This is happening with the latest FontForge from Fedora 9.
My intention is to add a few missing characters (U+0218, U+0219, U+021A and U+021B) to make the font compliant with the Romanian language and submit back the new version (I can do that using FontForge and TTFs, but I expect it is indicated to work on sources, .sfd).
This is a fontforge bug: https://bugzilla.redhat.com/show_bug.cgi?id=459451
Before fontforge package maintainer apply the patch and rebuild, you may compile fontforge locally with attached bug in above bug report.
