Translate ordinary text into the classic hacker l33t sp34k. Three intensity levels: 'Mild' replaces only the six most recognisable letters (a→4, e→3, i→1, o→0, s→5, t→7), 'Strong' adds b→8, g→9, l→1, z→2, and 'Maximum' replaces nearly every letter with a multi-character glyph mash (c→(, d→|), m→/\/\, w→\/\/, …). Case is normalised first since leet uses digits and symbols rather than capitalisation. Just-for-fun encoding, runs entirely in your browser.
