About this conversion

Basic mode swaps letters for look-alike numbers (a=4, e=3, i=1, o=0, s=5, t=7…). Advanced mode adds symbol forms (a=@, h=#, w=\\/\\/…). Leetspeak is a style, not a strict standard, so decoding only reverses the unambiguous number substitutions — symbol and mixed spellings can map back several ways.
