How the heck does this work?
Short answer: Unicode.
Slightly longer answer: It takes advantage of the Mathematical Alphanumeric Symbols Unicode block. A set of characters that fulfill Mathematicians’ need for consistent styles in their equations.
What is Unicode?
Unicode is the standardized system of computer characters. Read a better explaination here.
When should I use this tool?
Anywhere you want to use italics but typically can’t; for instance, you may want to use some Chandler-esque sarcasm on Instagram. Could that be anymore useful?
You might want to emphasize a word, or correctly format a citation in a tweet:
According to the original 1891 patent, toilet roll should hang over, not under.
Wrapping or Toilet Paper Roll — Patent No 459,516 | S. Wheeler
Without italics none of this subtlety would be possible.
Let me know if you find any more uses for this tool, as I’d like to create a longer article.
