Encoding other than (PlatformID = 0, Format = 4) is not yet supported

[lesept777]

The function CompileCmap in truetype.py has a warning:

      warnings.warn("Unimplemented: Encoding other than (PlatformID = 0, Format = 4) is not yet supported", Warning)

This limits the ttf files that can be transformed to vector fonts. Many other ttf files have different values, such as PlatformID = 1, Format = 0 Could you adapt your code so it can handle also these kind of font files?
