Tabulka 1. Bitmasks acceptable to iconv_mime_decode()

1ICONV_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.
2ICONV_MIME_DECODE_CONTINUE_ON_ERROR If set, iconv_mime_decode_headers() attempts to ignore any grammatical errors and continue to process a given header.


The optional charset parameter specifies the character set to represent the result by. If omitted, iconv.internal_encoding will be used.
