Multi Commander 3.5.1 build 1530
Create any file in russian, for example "тестовый документ с русскими буквами в названии.txt". In Windows Explorer (under Windows XP SP3) right click on that file and select Send to - Compressed zip folder. Now we get archive "тестовый документ с русскими буквами в названии.zip"
If we try to open such archive with Multi Commander, we see only inexplicable symbols instead of russian.
In other commanders (like Total Commander or FreeCommander XE) the same file is opened without any problems.
If we pack file "тестовый документ с русскими буквами в названии.txt" using Multi Commander in zip format, content of archive is shown correctly.
