## Uni-cat #unicode

### Expected solvable difficulty

• 1sample+: experienced solvers
• keywords+: most solvers

### 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.
