Iconv (filter)

The iconv filter converts 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);
