The iconv filter coverts between two charsets. It operates the same way in both decode and encode modes. On initialization, it takes two mandatory arguments:
- The name of the input charset
- The name of the output charset
Optional third argument specifies what to do when an illegal character sequence is encountered in the input stream. Its possible values are:
- none
- Return failure and stop further conversion.
- copy-pass
- Copy the offending octet to the output verbatim and continue conversion from the next octet.
- copy-octal
- Print the offending octet to the output using C octal conversion and continue conversion from the next octet.
The default is copy-octal unless previously overridden by a call to mu_default_fallback_mode function.
The following example creates a iconv filter for converting from iso-8859-2 to utf-8, signalling an error on the first conversion error:
int rc; /* Return code */
mu_stream_t flt; /* Filter stream */
char *argv[] = { "iso-8859-2", "utf-8", "none", NULL };
rc = mu_filter_chain_create (&flt, input, MU_FILTER_ENCODE, MU_STREAM_READ, 3, argv);
