Hi,
using Roundcube 0.5.1 I experience a strange behaviour:
I start a new conversation using a simple text containing "Umlaute", lets say:
äöüÄÖÜß
My partner answers me using Outlook 2007 (English version). The message I received is messed up when using Umlaut or other special characters. The message reads like this (my partner answered with 'äöüÄÖÜß' too, for demonstration):

äöüÃ,,ÖÜß
If I answer this message again and get another reply, everything is back to normal. So, msg #1, #2 are corrupt, msg #3, #4, ... are okay.
If I check the corrupt text using Thunderbird, all is okay and readable. When I check the source of the mail, I see that the answer of my partner (who's using Outlook) is base64 encoded. So I tried die decode using different web-tools. The "äöüÄÖÜß" I should receive is encoded to
77u/DQrDpMO2w7zDhMOWw5zDnw0K
Decoding "77u/DQrDpMO2w7zDhMOWw5zDnw0K" using PHP-Einfach.de - Base64 kodieren/dekodieren (http://www.php-einfach.de/base64_generator.php) (php based) comes out with crap. Using the javascript-based decoder at Kodierung und Dekodierung mit base64 (http://www.arndt-bruenner.de/mathe/scripts/base64.htm) gives the same messed up result.
But if I use the asp-decoder at Safe Base 64 Decoder (http://www.opinionatedgeek.com/dotnet/tools/base64decode/safedecode.aspx), it gives the correct result. The same if I use a windows executable program for decoding.
Countercheck: if i use a web-tool to encode "äöüÄÖÜß" I get 5Pb8xNbc3w== which should be the right base64 encoded result.
What I can say from comparing some mail sources is that the starting "77u/" seems to cause the trouble. It doesnt matter what text is encoded, if it starts with "77u/" it will decoded incorrect.
So what is the solution? And remember, the 3rd, 4th... reply of the message-thread is correctly showing umlaut and special chars.
Cheers & thnx in advance

It could be a unicode BOM (Byte order mark). Provide a sample message.

Here's a sample mail. I sent the starting mail with RC 0.5.1 to my girlfriend, and she answered using Outlook 2007, I guess (Englisch version). If I reply to that message and get an answer, the answer I can read normally, but msg #1 and #2 (see attachment) are still messed up.
I used Roundcube to save the .eml and the FAR built-in editor to edit & save the message.

Hm, you might be right with the BOM. I've just checked Byte order mark - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Byte_Order_Mark), and in the provide table there are the chars I always see at the beginning of a corrupt msg: "" (the representation of UTF-8 BOM in ISO-8859-1).
It works for me. BOM is removed by Roundcube properly. Maybe this is environment-dependent or config-dependent issue.

Ok, thnx. So I'll get in contact with my server admin. I found no solution/workaround for that issue on the net.
