CJK extensions

[Garygo1993]

Hi!

I am new around here, and I don't know if this is the correct way to post this, but I would like to participate in this project. I am not that good at graphic design, so I don't really feel comfortable making any new scripts or something, but I figured that I could help you (at least in part) with the CJK extensions, as that is mostly just modifying and combining existing glyphs. Till now, I have made the missing glyphs from CJK unified ideographs and CJK unified ideographs extension A in the regular thickness from the fonts on Google fonts, so I can send those files somewhere to see if the quality is satisfactory. Otherwise, I know most of the things about encoding of CJK characters (different designs for languages, variation selectors etc.) so that should not be a problem. I was thinking that I could make "extended" font that would be of a single thickness, but incorporate more characters.
