class TTFunk::SubsetCollection

Subset collection.

For many use cases a font subset can be efficiently encoded using MacRoman encoding. However, for full font coverage and characters that are not in MacRoman encoding an additional Unicode subset is used. There can be as many as needed Unicode subsets to fully cover glyphs provided by the original font. Ther resulting set of subsets all use 8-bit encoding helping to efficiently encode text in Prawn.
