| 23 | This is a simple example showing how a program on a non-ASCII platform |
| 24 | would invoke callbacks to do its own codeset conversions instead of |
| 25 | using the built-in iconv functions in libcurl. |
| 26 | |
| 27 | The IBM-1047 EBCDIC codeset is used for this example but the code |
| 28 | would be similar for other non-ASCII codesets. |
| 29 | |
| 30 | Three callback functions are created below: |
| 31 | my_conv_from_ascii_to_ebcdic, |
| 32 | my_conv_from_ebcdic_to_ascii, and |
| 33 | my_conv_from_utf8_to_ebcdic |
| 34 | |
| 35 | The "platform_xxx" calls represent platform-specific conversion routines. |
