Squared T-shirt sizes

[Doug Ewell]

JIS L 4004:2001 seems to refer to other two-letter size codes (PB, SA, SB, MY, MA, etc.) and does not enclose them in a square.

Encoding these as squared symbols would probably require substantial evidence that the symbols are already in use. The same would be true for the English S, M, L, XL... and any codes additionally specified in EN 13402.

Dear Unicoders

I was almost sure that I had seen squared XL and XS as ideographic legacy characters in the code charts before, but I can’t find them (e.g. in U+1F1xy or U+33xy), so I’m probably slightly delusional. XL is not included as a Number Form for the roman numeral of 40 (~ U+216x).

1. Did I miss anything?
2. Are such Latin size labeling characters (also LL or SS from JIS L 4004/4005) written within a single ideographic square in East Asia?
3. Could they be added to the standard without any such prior use?

Cheers,
