They also need a font. I tried to find the original, but in the end just asked Andrew West from BabelStone Han to redraw the characters for me.
It's a hobby project. Finding characters was a side effect of trying to scrape data for Pingtype https://pingtype.github.io (my Chinese learning program). When I tried to scrape characters from the Taiwanese Bible, I found inline JPGs and thought "that can't be right..." which led me down a rabbit hole ending here, exchanging emails with Richard Cook, Ken Lunde and John Jenkins (the world experts).

If you have access to a Chinese-language paper library, please try to help take photos of some characters. Search "please contact" on the BabelStone list for some urgent ones. For example, "U+F2DD Alternative character for Db (Dubnium)" and "U+F2E2 Alternative character for Rf (Rutherfordium)" could be easily found on a periodic table, I guess.
