-					 * Bits 5-10: These should be set according to

-					 * Bit 7: This bit should be set if the font

-					 * Bit 11: Font data is 'lossless,' as a result
-					 *   of having been compressed and decompressed

-					 * Bit 13: Font optimized for ClearType™.
-					 *   Note, fonts that rely on embedded bitmaps (EBDT)
-					 *   for rendering should not be considered optimized
-					 *   for ClearType, and therefore should keep this bit
-					 *   cleared.

-					 * generic symbolic representations of code point
