the missing third entry of the ⎕io←1/⎕io←0 merch is now available: ⎕io←÷2

APL386's claim of supporting "every special character used by any APL implementation" isn't true, it doesn't support, for example, ∂ from NARS2000

@RubenVerg I know. Bob Smith just wrote to me, asking for ∂ and fixing ∅. I hope to have a look soon.

@RubenVerg Nice. Please add it to apl.wiki/Merch after or between ⎕IO←0 and ⎕IO←1.

@Adám what description should I put?

@RubenVerg "⎕io←÷2" (index origin one half) and list the main categories of items, like the other entries in the table do.
