Force UTF8 Encoding from server side

[XenoBIT78]

hi

im running a glFTPd server and almost all users use FlashFXP so i thought that i might get an answer here..

i know it possible from a client to force UTF8 Character encoding using OPTS UTF8 ON.. if the server supports it ofc. but is it possible to do it the other way around? is there a server side command that forces clients to use UTF8 Encoding ??
