Re: Adding a new encoding to GNU C library

[Alexander Shopov <ash at contact dot bg>]

Hi glibc hackers,

I have looked into glibc sources, I am going to briefly outline what I 
suppose should be done to get MIK support:


1. Get MIK in iconvdata:
  - creating iconvdata/mik.c
  - include it in iconvdata/Makefile
  - include it in iconvdata/gconv-modules
  - test in testdata - MIK<->UTF-8,
    iconvdata/TESTS,
    iconvdata/tst-tables-sh

2. Get MIK in localedata
  - localedata/charmaps/MIK

Hopefully this is enough to get MIK. As we get the patches ready, I am 
going to send them for inspection.

Kind regards:
