mode
mode determines the behaviour in the event

MIME header field. You can specify any combination
of the following bitmasks.
| Value | Constant | Description |
|---|---|---|
| 1 | ICONV_MIME_DECODE_STRICT |
If set, the given header is decoded in full conformance with the
standards defined in » RFC2047.
This option is disabled by default because there are a lot of
broken mail user agents that don't follow the specification and don't
produce correct MIME headers.
|
| 2 | ICONV_MIME_DECODE_CONTINUE_ON_ERROR | If set, iconv_mime_decode_headers() attempts to ignore any grammatical errors and continue to process a given header. |
charset
The optional charset parameter specifies the
character set to represent the result by. If omitted,
iconv.internal_encoding
will be used.
Returns a decoded MIME field on success,
or FALSE if an error occurs during the decoding.
