Bitmasks acceptable to iconv_mime_decode()
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.

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.
