This class merges multiple files into a single OpenType font, taking into account complexities such as OpenType layout (``GSUB``/``GPOS``) tables and cross-font metrics (e.g. ``hhea.ascent`` is set to the maximum value across all the fonts). If multiple glyphs map to the same Unicode value, and the glyphs are considered sufficiently different (that is, they differ in any of paths, widths, or height), then subsequent glyphs are renamed and a lookup in the ``locl`` feature will be created to disambiguate them. For example, if the arguments are an Arabic font and a Latin font and both contain a set of parentheses, the Latin glyphs will be renamed to ``parenleft#1`` and ``parenright#1``, and a lookup will be inserted into the to ``locl`` feature (creating it if necessary) under the ``latn`` script to substitute ``parenleft`` with ``parenleft#1`` etc. Restrictions: - All fonts must have the same units per em. - If duplicate glyph disambiguation takes place as described above then the fonts must have a ``GSUB`` table.
