The history of luaTEX 2006–2009 / v 0.50 - Pragma ADE

This gives:
f i fi ffi
f i fi ffi
ffi ffi ffi
We are quite tolerant with regards to this specication and will provide less dense methods
as well. Of course we need to implement a whole bunch of features but we will do
this in such a way that we give users full control.
encodings
By now we've reached a stage where we can get rid of font encodings. We now have
the full unicode range available and no longer depend on the font encoding when we
hyphenate. In a previous chapter we discussed the difference in size between formats.

The size of the formats has grown a bit due to a few more patterns and a extra preloaded
encoding. But the LuaTEX format shrinks some 10% now that we can get rid of encoding
support. Some support for encodings is still present, so that one can keep using the
metric les that are installed (for instance in project related trees that have special fonts)
although afm/Type1 les or OpenType fonts will be used when available.
A couple of years from now, we may throw away some Lua code related to encodings.
les
TEX distributions tend to be rather large, both in terms of les and bytes. Fonts take most
of the space. The merged TEXLive 2007 trees contain some 60.000 les that take 1.123
MBytes. Of this, 25.000 les concern fonts totaling to 431 MBytes. A recent ConTEXt
distribution spans 1200 les and 20 MBytes and a bit more when third party modules are
taken into account. The fonts in TEXLive are distributed as follows:
format les bytes
AFM 1.769 123.068.970 443 22.290.132
TFM 10.613 44.915.448 2.346 8.028.920
