As I implemented WebDAV server to share data sometimes I need to give users an HTTP link for WebDAV file or folders (the reason for that is that Windows XP clients can't open some file types, PDF for example, right from connections created in the Network Neighborhood). Everything work fine, exept that by default Apache generates file and folder listing using default encoding ISO-8859-1. In my case this is not appropriate: I need to publish files with Russian filenames. My collegue help me with this solution:
in file /etc/httpd/conf/httpd.conf add second line and comment the first
#IndexOptions FancyIndexing VersionSort NameWidth=* HTMLTable
IndexOptions FancyIndexing VersionSort NameWidth=* HTMLTable Charset=UTF-8
Now I can get file and directory listing in right encoding. Thank you Lena!
