--- Comment #3 from Nicolas Mailhot nicolas.mailhot@laposte.net --- Of course some font makers DO expect apps to understand Bold when they use some other hipster designation. It works in their Apple apps (and they did not test anything else).
What can I say, you want apps to understand Bold you state Bold in the face name, simple easy, stupid and reliable.
