With the Macintosh OS, you actually have resource forks, and other hidden areas of the file... The user doesn't see these areas, but the applications can store data there. These fonts are storing their font data in a resource fork.... And windows doesn't understand what the resource fork is...
So, if you want to use a cross-platform font, use a TrueType Font... The Mac will be able to read just about any particular type of font, so you don't have to limit yourself... If there is any doubt about a replacement font, just test it in Fontbook.
