FAQ
What is L33t speak?
L33t, or leet, is a writing style from the early internet hacker scene that swaps letters for lookalike digits and symbols, such as 3 for e, 4 for a, and 0 for o.
Does it convert Chinese text?
L33t speak is a set of substitutions for the Latin alphabet, so only English letters are converted. Chinese characters are left exactly as they are.
What do the intensity levels change?
The light level swaps only the handful of most common letters. The heavy level replaces every substitutable letter, which looks far more striking but is harder to read.
Where do people use this?
Typically in gaming handles, social media nicknames, and playful slogans, and sometimes for decorative code comments or humor in technical communities.
