Cryptanalysis & Frequency Analysis
Character frequency analysis is widely used in linguistics and deciphering substitution ciphers (e.g., "E", "T", and "A" are historically the most frequent letters in English).
Whitespace & Punctuation Options
Customize whether spaces, line breaks, or punctuation marks are factored into frequency percentages, isolating strictly alphabetic letters if needed.
