The wiki says it fits the description, just as I submitted in post #2093189

But then I see many other examples listed for character that have symbol-shaped_pupils.
I think there is a clear difference, because one related to a facial expression and the other is a visual trait.

Maybe it should be said the +_+ tag should represent eyes entirely in the shape of star, rather than just the pupils.

Sounds good to me. The pupils could be moved to a new tag, perhaps plus_sign-shaped_pupils.

I think the issue here is because the wiki mentions as an example 'eyes like Nia Teppelin' which is basically symbol-shaped pupils.

Alright. I will make the changes then.

(sorry for the strange formatting below, but I can't do it any better with DText)

The current situation is actually quite complicated:

			+_+ (trait)	+_+ (expression)	diamond (expression)	star (trait)
+_+			yes		yes [1]			no			no
star-shaped_pupils	yes		yes [2]			no			yes
diamond-shaped_pupils	no		yes [2]			yes			no

[1] whole eyes or only pupils
[2] only pupils

definitions:

+_+ = four-pointed star ✦

diamond = diamond ♦

star = five (or more) pointed star ★

• diamond (trait) and star (expression) are not included because I didn't find any images fitting that category
• +_+ contains the aliases cross-shaped_pupils, star_eyes, starry_eyes, see topic #8812, topic #2919
• star-shaped_pupils and diamond-shaped_pupils implicate symbol-shape_pupils (+_+ does not)

I'm not sure what's the best way going forward. It would be nice to more clearly separate these cases, but it would require manually changing the tags on a lot of posts and what's even more difficult is how to make sure that users actually use the correct tag in the future.

That shape on its own is usually tagged as sparkle. I would consider them "sparkle-shaped pupils".

Though eyes like nia_teppelin, hibari_(senran_kagura), and tachibana_sylphynford look more like flower petals to me. There are some instances in flower-shaped_pupils that look similar (some with more than four points), though many look more obviously flowery.
