Ortography
One of the hallmarks of Leet is its unique approach to orthography, using substitutions of other characters, letters or otherwise, to represent a letter or letters in a word.For more casual use of leet, the primary strategy is to use homoglyphs, symbols that closely resemble (to varying degrees) the letters for which they stand.
However, this practice is not extensively used in regular Leet, more often it is seen in situations where the argot characteristics of the system are required, either to exclude newbies or outsiders in general. Another use for Leet orthographic substitutions is the creation of paraphrased passwords.By using this method, one can create a relatively secure password which would still be easily remembered.
