Different platforms have different levels of support of encodings and
often have slight variations. We already have tables for most encoding
with only CJK missing. Full transcoding inclusion allows us to get reliable
encoding results independently of platform. The biggest con is the need for
external tables encoding.dat.
It removes a duplicate table for korean in graphics/korfont.cpp
MSVC8 gives various compile error relating to templates that were changed
back in 2008, leading me to belive that no one is using it, and that there
is not point adding work arounds for a 9 year old compiler no one uses.
