cover evasions from unicode substitutions
Add variations to cover unicode substitutions to avoid evasion.

> Unicode contains a range for Spacing Modifier Letters (0x02B0 - 0x02FF) [4], which includes characters such as ˪, ˣ and ˢ. Some command-line parsers recognise these as letters and convert them back to l, x and s respectively.
