This is from the friend of mine who invented TrueType fonts ... I sent him Mark's question: ".. the font question, the embedding privileges are stored in a field in the font's OS/2 table. Since Apple doesn't use the OS/2 table, its documentation is a bit out of date. Here's a link to the MS page describing the fsType field (where the embedding info is stored): http://www.microsoft.com/typography/otspec/os2.htm#fst There are tools that can show this value and otherwise deal with it, but honestly, it's probably easier to just do it directly from the command line. Launch Terminal, and navigate to the directory containing the font in question. First, do this (this example uses a font called fred.ttf): $ xxd -l 64 -u fred.ttf This will produce a few lines of output, like this: 0000000: 0001 0000 0012 0100 0004 0020 4F53 2F32 ........... OS/2 0000010: 6926 F3EC 0001 56CC 0000 0060 636D 6170 i&....V....`cmap 0000020: 8E1F 46FD 0001 07D4 0000 05A6 6376 7420 ..F.........cvt 0000030: 0023 0011 0000 EEAC 0000 0006 6665 6174 .#..........feat See the end of the first line there, where it says OS/2? That's the directory entry for the OS/2 table. That tag comes first, then a 4-byte checksum, and then the 4-byte offset to the table, which is 0x000156CC here. The fsType field is always 8 bytes from the start of the OS/2 table, and extends for 2 bytes. Adding 8 to 0x000156CC we get 0x000156D4, which is the offset of our value. Look at it via this command: $ xxd -l 2 -s 0x156D4 -u fred.ttf This finally gives you the embedding value: 00156d4: 0000 .. You can interpret the bits via the documentation linked to above."
