Cyrus + php Net/IMAP & encoding

[Pieter Vanmeerbeek]

Hi,

I'm struggling with the encoding of my cyrus installation.

I have a folder Calendar Partagé , which is stored and known  by cyrus as
'user/pv/Calendrier partag&AOk-'


However the same folder needs to be consulted by a php process, using
Net/IMAP.php module.

The default setting for this  module is a special utf_7 + base 64 encoding
(which seems to be declared by RFC 3501).

If I try to access this folder using the module I'm getting an error : 

Error: Folder: user/pv/Calendrier partagé, [pear_error: message="NO, Mailbox
does not exist" code=0 mode=return level=notice prefix="" info=""]


Further investigation shows that the php module encodes the folder name to
"user/pv/Calendrier partag&w6k-", which differs from the cyrus storage
format.

Manually setting the foldername to the storage format of cyrus does the
trick. 

Is there anyone experiencing the same problem as I am? 


I'm using PHP 4.4.2, cyrus 2.2.12, Net_IMAP 1.0.3.


Kin regards
Pieter




PS this is the encoding from php : 
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>

     function utf_7_encode($str)
    {
        if($this->_useUTF_7 == false ){
            return $str;
        }
        //return imap_utf7_encode($str);

        $encoded_utf7 = '';
        $base64_part  = '';
    if(is_array($str)){
        return new PEAR_Error('error');
    }


        for ($i = 0; $i < strlen($str); $i++) {
            //those chars should be base64 encoded
            if ( ((ord($str[$i]) >= 39 ) and (ord($str[$i]) <= 126 )) or
((ord($str[$i]) >= 32 ) and (ord($str[$i]) <= 37 )) ) {
                if ($base64_part) {
                    $encoded_utf7 = sprintf("%s&%s-", $encoded_utf7,
str_replace('=', '',base64_encode($base64_part))  );
                    $base64_part = '';
                }
                $encoded_utf7 = sprintf("%s%s",$encoded_utf7 , $str[$i]);
            } else {
                //handle &
                if (ord($str[$i]) == 38 ) {
                    if ($base64_part) {
                        $encoded_utf7 = sprintf("%s&%s-", $encoded_utf7,
str_replace('=', '',base64_encode($base64_part))  );
                        $base64_part = '';
                    }
                    $encoded_utf7 = sprintf("%s&-", $encoded_utf7 );
                } else {
                    $base64_part = sprintf("%s%s",$base64_part  , $str[$i]);
                    //$base64_part = sprintf("%s%s%s",$base64_part , chr(0)
, $str[$i]);
                }
            }
        }
        if ($base64_part) {
            $encoded_utf7 = sprintf("%s&%s-", $encoded_utf7,
str_replace('=', '',base64_encode($base64_part))   );
            $base64_part = '';
        }
        return $encoded_utf7;
    }
