After two weeks finally the problems have been solved. Thanks again to those who helped out.
EasyTimeline can now be run on UTF-8 sites, but only displays the extended ASCII character set so far. Full unicode support using external fonts will come later this year. Also annoyingly the internal font used by Ploticus (which does the rendering) misses a few common accented characters, like รจ. These will be replaced by unaccented chars for the time being.
