I have a requirement to patch the Lua core to handle different code pages.
The code pages will mainly be EBCDIC but could be ASCII.
I've had a look at the code and it seems that I can hook  iconv() calls into
luaL_loadfile, LuaL_loadbuffer and LuaL_loadstring in lauxlib.c, which
should translate all the source code before it hits the lexer/parser.

Is there a better way of doing it?
Customize lctype.c?

Needs to be done at runtime. Something like:

 lua -encoding=ibm-037 <script>
