No the .conf file is just a configuration file.
I just had a look in the .conf file and it looks like this:
Code:
# UTF-8 support for file names (RFC 2640)
# Set the charset of the server filesystem and optionally the default charset
# for remote clients that don't use UTF-8.
# Works only if pure-ftpd has been compiled with --with-rfc2640
# FileSystemCharset big5
# ClientCharset big5
So I guess you have to remove the # characters, change big5 to utf-8 save and then restart pure-ftpd.
The options lines is online for in the boot script.
Recompiling is done with the custom script by adding the
--with-rfc2640
line, so also not with the Options line.
