unicode correctness
Unicode in titles and labels doesn't appear to be handled correctly. In my case (using the gtk version), they are simply not displayed.
I looked into this and it seems to be an issue inside GtkD or with font selection. Plot2Kill doesn't do any string processing on the labels before sending them to GtkD's Cairo API to be rendered, so there's nothing to go wrong at that level. The GtkD documentation for drawing text paths says it supports Unicode. I'm not sure the default fonts I chose for Plot2Kill do, though. Could you please try a few different fonts that you know should work with Unicode and see what happens?
