Well the question is: Is it allowed to "extract" Data from .Net if it can be 
extracted using a normal application (I attached an application that might 
be suited for the task)

This would be a perfect size.

Do you mean something like: private static readonly byte[]...?
This seems to come with some overhead for me. Also it doesn't seem to 
produce shareable memory between processes.
So the idea was (see original mail) to embed the datatables as resources 
into the corelib assembly.

Currently the I18N assemblies are about 1MB IL-compiled in size. About 98% 
is IL-Code, 1-2% is static data.
With the suggested implementation we would have (for single byte encodings) 
basically 0% IL and 100% resource-data.
My MS.Net has 145 encodings, mono currently has 95 total.
Each (single-byte (approx. 95 in MS.Net)) encoding would have about 65kb of 
tables (the idea is to create one resource per encoding)
