According PHP documentation imap_utf7_decode() returns "the decoded
8bit data", but documentation says nothing about encoding of returned
"8bit data". When I try decode folder with name 'test&AN9ZJw-',
imap_utf7_decode() returns following string:
0x74, 0x65, 0x73, 0x74, 0x00, 0xDF, 0x59, 0x27
It looks as UTF-16 (UCS-2) string with missed '0x00' for ASCII
characters. If I'm right and imap_utf7_decode() returns UTF-16 string,
this string should be represented as:
0x00, 0x74, 0x00, 0x65, 0x00, 0x73, 0x00, 0x74, 0x00, 0xDF, 0x59, 0x27
To fix this this problem I wrote patch for ext/imap/php_imap.c and
attache it to this posting.
Best regards,
Gamid Isayev
