Mac OS X's Font Book application displays samples for each font installed on the system. For Latin-alphabet fonts it displays the uppercase and lowercase Latin alphabet; for Asian fonts it displays Asian characters, and so on. When I select DejaVu Sans the sample displayed is either Arabic (for Bold and Book) or another alphabet (Cherokee?) (for Bold Oblique and Oblique). This does not affect the performance of the font itself, as far as I can tell, but it highly annoying and unusual.

That's Font Book behaviour that we cannot control. The multiple scripts in DejaVu makes it think that the base script of the font is Arabic in the left screenshots or Armenian in the right ones. It would be better for Font Book to notice that there is more than one script besides Latin and it should default to Latin then. Anyway, it can only be fixed in Font Book, nothing we can do to make it display Latin. Greetings, Ben
