Back in my day... They didn't have emojis in terminals.

U+263A entered Unicode in 1993, afaik. Plan9 had utf8 support in the terminal back then!

Single code point, monochrome and single space. So it didn't need to be handled differently than any other non-ASCII character.

BTW, it is emitted with the sequence `Compose` `:` `)` (if you have Compose-key support installed+enabled)

This character was code 0x01 in the original IBM PC code page (https://en.wikipedia.org/wiki/Code_page_437), and hence in DOS. It was displayed single-width and monochrome just like any other 8-bit character, never causing any rendering issues, unlike emojis today. It was added to Unicode for round-trip compatibility with that code page.

UTF-8 was developed by Rob Pike and Ken Thompson on a napkin in a diner and implemented in Pikes Plan 9 making it the first UTF-8 OS.
