-// so the [^a-z]* means that if someone does 'n..i..g..g', then the 0 or more non-alphabet
-// characters between the n, i, g, g are still matching. Note that it's 0 or more, not 1 or more, so 'nigg' still matches.
-// the [il1|] set is just common replacement characters for i that will be used in evasion. I'll add accents later.
