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.
| Character | Unicode Name | CC meaning |
|---|---|---|
| 🅭 | U+1F16D Circled CC | Creative Commons Logo |
| 🅯 | U+1F16F Circled Human Figure | BY: Credit must be given to the creator |
| 🄏 | U+1F10F Circled Dollar Sign with Overlaid Backslash | NC: Only noncommercial uses of the work are permitted |
| 🄎 | U+1F10E Circled Anticlockwise Arrow | SA: Adaptations must be shared under the same terms |
| ⊜ | U+229C Circled Equals | ND: No derivatives or adaptations of the work are permitted |
| 🅮 | U+1F16E Circled C with Overlaid Backslash | PD: Release to Public Domain |
| 🄍 | U+1F10D Circled Zero with Slash | CC0: Creative Common’s Public Domain license |
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.
| Characters | Unicode Name | Source |
|---|---|---|
| 🮹🮺 | 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
- 〳
〵 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.
