imap_utf7_decode -- Decodes a modified UTF-7 encoded string

Description

string imap_utf7_decode ( string text )

Decodes modified UTF-7 text into ISO-8859-1 string.

Returns a string that is encoded in ISO-8859-1 and consists of the same sequence of characters in text, or FALSE if text contains invalid modified UTF-7 sequence or text contains a character that is not part of ISO-8859-1 character set.

This function is needed to decode mailbox names that contain certain characters which are not in range of printable ASCII characters.

The modified UTF-7 encoding is defined in RFC 2060, section 5.1.3 (original UTF-7 was defined in RFC1642).

For "Outlook-style" UTF-7, you can also use:



mb_convert_encoding( $str, "ISO_8859-1", "UTF7-IMAP" ); # for decoding

mb_convert_encoding( $str, "UTF7-IMAP", "ISO_8859-1" ); # for encoding

imap_utf7_decode decodes 'modified'.


For decoding Outlook UTF-7 - texts I use --enable-recode and $latin1string=recode_string("UTF-7..ISO_8859-1",$utf7string);


Don't use recode-3.5c.*rpm from Contrib.


recode_string seems to be buggy.
