/*
|
|
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.
