/*

   This is a simple example showing how a program on a non-ASCII platform

   would invoke callbacks to do its own codeset conversions instead of 

   using the built-in iconv functions in libcurl.

   The IBM-1047 EBCDIC codeset is used for this example but the code

   would be similar for other non-ASCII codesets.

   Three callback functions are created below:

        my_conv_from_ascii_to_ebcdic,

        my_conv_from_ebcdic_to_ascii, and

        my_conv_from_utf8_to_ebcdic

   The "platform_xxx" calls represent platform-specific conversion routines.
