There are a lot of symbols under the new Symbols for Legacy Computing Supplement block. Some of them are very tricky to make (like the outlined letters -- we MAY need to build an automated outlining algorithm to generate these).

A quick progress report: After #2293, these symbols are left to be implemented, categorized by their shape:

Dots

• [ ] Speckles 𜱆𜱇
• [ ] Explosion 𜷽𜷾𜷿 The laziest implementation is probably to implement them like mosaics (and hardcoding each dots), but there might be better ways.

Terminal shapes

• [ ] Non-round voided cross 🯋
• [ ] Black Small Chevron 🯍 Both have a close equivalent 🯀🯊 so implementations depend on them. Not sure how.

Symbols with curves

• [ ] Curved Gates 𜰕𜰖
• [ ] Coil 𜰋𜰌𜰍

Game sprites without curves

• [ ] Rocket 𜱖𜱗𜱘𜱙
• [ ] Moon Lander 𜷵
• [ ] Rocket Booster? 𜲠𜲡 (Looks like a teletext mosaic to me)
• [ ] Roller Coaster? 𜲢𜲣

Game sprites with potentially simple curves

• [ ] Rifle 𜱥𜱦𜱧𜱨
• [ ] Bassinet 𜱈𜱉
• [ ] Tank 𜲞𜲟
• [ ] Bomb 𜱠𜱡𜱢𜱣
• [ ] UFO 𜲤𜲥

Game sprites with harder curves

• [ ] UFO? 𜱊𜱋
• [ ] Aliens 𜱌𜱍𜱎𜱏𜱐𜱑𜱒𜱓𜱔𜱕
• [ ] Storm cloud 𜱤 (or depending on interpretation, a pinball plunger)
• [ ] Fish and bird𜲒𜲓𜲔𜲕𜲖
• [ ] Turtle 𜷻𜷼
• [ ] Big human sprite 𜷦𜷧𜷨𜷩𜷪𜷫𜷬𜷭𜷮𜷯

Straight-up emoji

• [ ] Planes 𜷸𜷹𜷺

There are also the non-legacy ✈🛧 that are supposed to be a part of the set, so they will have to look consistent.

Big chess pieces

• [ ] 𜲺𜲻𜲼𜲽𜲾𜲿𜳀𜳁𜳂𜳃𜳄𜳅𜳆𜳇𜳈𜳉𜳊𜳋𜳌𜳍𜳎𜳏𜳐𜳑

This guy

• [ ] Standing knight

  𜳒𜳓
  𜳔𜳕

  Literally the only usage I've seen is as an icon for a game producer for the Sharp MZ console.

I'm just putting this here because I'll probably run out of things that I can implement soon. I'll need help for the rest.

Some of them may worth just drawing them using any vector graphics software then import them...
