Level design

This level is inspired by a (back then) recent version update to Unicode – Unicode 13. In this version, a lot of new scripts and glyphs are added to the code chart. In the first 2 questions, I’ve chosen 2 set of characters that are rather interesting.

For the first one, they are 🅭🅯🄏🄎, a series of characters are added to represent a configuration of Creative Commons licenses.

The second part of the question is taken from the segment of the new Symbols for Legacy Computing block, which as the name suggests, included a few characters from legacy character encoding.

CharactersUnicode NameSource
🮹🮺U+1FBB9 Left Half Folder
U+1FBBA Right Half Folder
From Apple II 0x58, 0x59
🯁🯂🯃U+1FBC1 Left Third White Right Pointing Index
U+1FBC2 Middle Third White Right Pointing Index
U+1FBC3 Right Third White Right Pointing Index
From TRS-80 0xF4, 0xF5, 0xF6
🮲🮳U+1FBB2 Left Half Running Man
U+1FBB3 Right Half Running Man
From Apple IIc 0x46, 0x47

To learn more about those characters, take a look at the L2/19-025 proposal of the new block to Unicode.

Interestingly, these characters adds to the list of Unicode characters that are designed to build a single shape (instead of drawing arbitrary shapes) from multiple characters. Other examples of such characters include:

  • ⯨⯩ Left/Right Half Black Star, U+2BE8 U+2BE9

  • Vertical Kana Repeat Mark Upper/Lower Half, U+3033 U+2025

  • Top/Bottom Half Integral, U+2320 U+2321

Expected thought process

Notice the questions are asking was to identify the character shown in the picture, and most of these characters are new in Unicode 13. Look up for the characters in the question among the new characters added in the version, and get their hexadecimal index.

Trivia

Typefaces used to render the questions are CC Symbols and BabelStone Shapes. Noto Sans Symbols2 is used on this page instead of BabelStone Shapes.
