[syslog-ng] Syslog-NG and UTF-8 problem.

Hello. I forward my Windows event logs to my Linux Box. I guess the Syslog-NG that I installed it on my Linux box can't support UFT-8 because when the file or folder names are English then I can't see them. In my Windows Box, I'm using "nxlog" that it support UTF-8. How can I add UTF-8 feature to my Syslog-NG on Linux? Thank you.
