libfontembed - font embedding and subsetting library
----------------------------------------------------

This library implements all the stuff required to
embed and subset TrueType fonts, as for example
required in PDF files. It is completely self-contained,
although a FreeType binding might come sometime in the future.

Currently glyf-flavored TrueType is fully supported,
but for OTF, i.e. CFF-flavored TrueType/OpenType, subsetting is
not done; embedding does work.
And single-byte mode does needs work/thought wrt. to encodings.
Also reencoding and conversion of Type1 to CFF is planned.
PostScript embedding is another goal of the project.

Additionally, wOFF-support can be compiled in and
better CFF support being worked on.

The most important issue that needs fixing is support for
text extraction in the PDF multibyte case (most common),
which requires ToUnicode support; some preparation is already done.

Usage
-----
(TODO)... see test_pdf.c ...

 * for direct sfnt access: use <sfnt.h>
 * for embedding: use <embed.h>  (which includes <fontfile.h>)
