While importing mail-messages from PST-files Russian (Cyrillic) names of attachment files are presented in codepage ISO and as a result they are deformed. There is abracadabra instead of letters.
If the mail with an attachment comes and the attachment is a file with a name in Russian, everything is all right. Russian letters are displayed normally. I think, that a problem in ZCSImportWiz.
Whether It is possible hopes, what the problem will be solved? Otherwise migration on Zimbra the Russian-speaking countries will slowly occur.
I use ZCSImportWiz-4.5.0_GA_611.exe on OS Windows XP SP2 RUS. Server Zimbra is deployed on the server under control of Fedora Core 6 with locale LANG=ru_RU.UTF-8.
