Feature/replace regex #10

Open nastymorbol opened 1 year ago

nastymorbol commented 1 year ago

Replaced some Regex with constant expressions for performance improvement.

I considered making similar changes, but was going to recommend using the built it char static functions instead. Specifically, char.IsAsciiDigit or char.IsDigit, char.IsAsciiLetter or char.IsLetter etc.

Since the static char functions are unicode, i prefer to work with explicit ASCII characters. Unfortunately, I already had problems where my customers used some unicode characters using copy paste, which I then misinterpreted.
