I've noticed some strange behavior when using Font Awesome inline icons.

1) Some icons get mirrored horizontally.
The icon "ambulance" for example is shown driving to the right on Font Awesome. However, as an inline icon in the HTML output it drives to the left. (by the way, in ASCIIDoctor-PDF's output the ambulance drives to the right, as expected).

2) Some icons don't show
I could not yet find a rule to this behavior but some of the icons just don't show on the HTML page (even though the code is embedded correctly in the HTML source).
Working: bullseye, bullhorn, comments
Not Working: mail-bulk, comments-dollar, lightbulb
It seems to me like all the icons that have a hyphen in their name don't show. However, the lightbulb is written without a hyphen and still doesn't show so I'm not sure what the pattern is here.
