[SM-STABLE] damaged folder names in national charset

[Inna K. <id...@md...>]

Dear colleagues,

I'm using RH 9.0, Apache 2.0.45, PHP 4.3.2RC4, SM 1.4.2, including =
plugins: 'abook_take'; 'calendar'; 'delete_move_next'; 'info'; =
'message_details'; 'newmail'; 'spamcop'; 'squirrelspell'; =
'abook_import_export'; 'archive_mail'; 'block_sender'; =
'folder_settings'; 'folder_sizes'; 'quota_usage'; 'show_user_and_ip'; =
'show_headers'; 'timeout_user'; 'weather'; 'compatibility'; =
'mail_fetch'; 'filters'; 'password_forget'; 'time'; 'view_as_html'.
The system is working fine except one problem with folder's names in =
russian charsets. I mean subscription for folders from MS Exchange 2000 =
(RUS) database. When folder with russian name is created from MS =
Outlook, it cannot be read from SM in any charset. I see only =
abrakadabra like "'5@=3D>28:8". And, vice versa, if you created folder =
in russian from SM you'll see from MS Outlook something like =
&BB4EQgQ,BEAEMAQyBDsENQQ9BD0ESwQ1. It seems to be broken while =
encoding/decoding.=20
If nobody have a solution, please, give me any tips for improving the =
code. As I guess, the thing is in the functions =
imap_utf7_decode_local/imap_utf7_encode_local, isn't it?

Regards,
