--noupnp => Disable UPnP subsystem
--perfmon => Enable internal server performance monitoring
--perfwarn => Generate log messages if internal tasks take
longer than specified threshold
--failsafe => Don't load plugins
--checkstrings => Enable reloading of changed string files for
plugin development
--charset => Force a character set to be used, eg. utf8 on
Linux devices
which don't have full utf8 locale installed
