I know, but it's fine: most people could esily remove them and many more
people wouldn't care less for 200 KB more. Remember, we used to inflict
20+ MB of ICU on them:-)

It can be done in two ways: embed the files in the mono binary like we do
with the char tables or load the files from where mscorlib was loaded.
Both are trivial to implement.

It means minimal correct support for unicode chars 0-255 in the
invariant locale (maybe plus another configurable locale that only
uses those chars). Of course if this still requires 120 KB of data it's
not worth it. If it requires 10-20 KB it would be nice to have it as
an option. But there is no hurry for this, just keep it in mind as
we may be asked to implement it.
