By adding char encoding to ruby ​​1.9.x?

Question

If you need to add a new char encoding in 1.9.x, which is supported in the same way as built-in encodings, how would you do this? Can you do this with a ruby ​​code, or will he need patch C in MRI?

(I don't think it matters, but I'm interested in the Marc8 encoding, an old obsolete encoding that is still used in libraries (like books), systems, and records.)

Answer 1

I would recommend to see how it is implemented in Ruby 1.9.2. Basically dig the source code and ... :-)

This is a similar question: Create your own encoding
