 |

 * 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.
