Was working on the Doppo_is_pissed!! wiki when I noticed that なんだァ?てめェ…… (the most populated Pixiv tag equivalent) couldn't be (practically) added to "other names" section because the double Japanese three-dot ellipses get turned into six sequential periods/full stops. The field 'accepts' the name anyway but since it's a different name, it's pointless for Pixiv searches and tag completion, so I removed it.
I don't think it's necessary to allow the three dot … in wiki "other names", but perhaps this should fail gracefully instead of introducing unexpected changes? By rejecting the name outright instead of changing it into a subtly-different one that will likely be missed unless the wiki writer doublechecks the links, I mean.
