I downloaded this and had a look at it.  In the file NOTES, it talks
about which encodings are supported.  EBCDIC support doesn't seem to
be a goal:

  Q: Support EBCDIC ?
  A: No!

Still, it's licensed under the LGPL, and it looks easy to add new
single-byte encodings.

I've looked into this some more, and it looks like it should at least
be possible to use nl_langinfo() to get an encoding to use.  If it
actually matters to someone what encoding they use, they should
probably have $LANG set anyway.

----------------------------------------
/* langinfo.c */

#include <stdio.h>
#include <stdlib.h>
#include <locale.h>
#include <langinfo.h>

int
main(int argc, char **argv)
{
    const char *lang, *codeset;

    lang = (argc >= 2) ? argv[1] : "";
    setlocale(LC_ALL, lang);
    codeset = nl_langinfo(CODESET);
    printf("codeset = '%s'\n", codeset);

    exit(0);
}
----------------------------------------

$ ./langinfo C
codeset = 'ANSI_X3.4-1968'
$ ./langinfo en_NZ
codeset = 'ISO-8859-1'
$ ./langinfo hr_HR
codeset = 'ISO-8859-2'
$ ./langinfo ru_RU
codeset = 'ISO-8859-5'
$ ./langinfo ru_RU.KOI8-R
codeset = 'KOI8-R'
