I’m not 100% sure.
I’m working on a custom Anki deck to supplement my use of the main Wanikani app.
I’m intentionally skipping radicals that are listed as “kanji” on this list (I probably should’ve mentioned that in the first place come to think of it).
Out of the radicals that I am not skipping, before, icicle, proclaim, and wheat did not come up with svg files (or at the least my script didn’t get svg files for them from the API, it might be a problem with my script).
EDIT: While the above is true, my initial script getting the SVGs was not set up to skip those radicals, so nevermind about that.
I just went through and manually created SVG files for those four radicals and then converted them into PNGs, so those are no longer missing.
I’d be happy to add any missing radicals to the repository.
