Nice. I've started picking up F# too and am trying AoC with it this year. I'm still early in my functional journey, but I think AoC has been helpful thus far.
Hmm, good observation. I guess the site supports Hepburn-romanized names. I believe adding support Kunrei-shiki and maybe Nihon-shiki names too would resolve this issue pretty well.
Given that it's an English site, I'm unsure of the value of supporting the original Japanese names too, but of course it would be neat if it did.
