About the Character Frequency Counter
Frequency analysis is the classic first move against substitution ciphers — in English text "e" dominates at roughly 12%, so the most common symbol in a ciphertext is a prime suspect. It is just as handy for everyday work: spotting stray characters in a data export, checking whether a string is ASCII-clean, or seeing which punctuation a writer overuses.
Every distinct character gets a row with its raw count and its density — the percentage of the total it accounts for — plus a small share bar for visual scanning. Toggle spaces on to include them (shown as ␣) or off to focus on visible glyphs.
