Reference files are now saved as UTF-8. Existing files have yet to be converted, however simply load/save in the editor to do this. For some reason I’ve had trouble with utf-8 smart quotes/apostrophes so these are automatically replaced with html entites for now (hopefully once I’ve figured out exactly what’s going on utf-8 smart quotes will be natively supported). Microsoft proprietary smart quotes/apostrophes/hyphens are likewise converted to html entities though would prefer to make them utf-8 characters.
Likewise SEL files are now saved as utf-8.
