Level design

Following the trend of “exploiting” Unicode for level ideas, I found another property of characters in the chart – Category. Unicode broken down all their characters into 29 categories and 8 groups – Letter, Mark Number, Punctuation, Symbol, Separator, and Other. Each of the category has a two-letter acronym, for instance, uppercase letters are Lu, and currency symbols are Sc. The characters in the question are chosen from random online Unicode “font” converters websites and handpicked for a wider variety of categories.

Expected thought process

Realizing this question is asking for Unicode Category acronyms from samples or keywords provided, and look them up in Unicode databases.

Trivia

Recovering the ASCII plain text from the questions, dQw4w9WgXcQ, j8PxqgliIno, YddwkMJG1Jo, and xvFZjo5PgG0 are four different Rickrolling video links on YouTube, with the first being the most famous one.
