The font is not called "OpenDyslexics", it's "OpenDyslexic". Also, it's kind of odd to say you support multiple dyslexic-friendly fonts when it's really just one font in bold/italics/mono. Perhaps some people would consider mono to be its own font (though I've never known anyone who preferred OD Mono, and I work in the accessibility world). But for sure bold and italic are not considered to be separate fonts by lay people.
