This is not problem if we will have some common API. You can use current conversion tables (maps) and for example I can
useiconv on my i386/Linux.
 
I don't want to replace current maps if somebody needs it. I wouldlike to API.
I see iconv is included into glibc now.

How knows this function to/from encoding?
