FAQ

What is character frequency used for?

In cryptanalysis, letter frequency helps break substitution ciphers. In linguistics, it reveals language patterns. In SEO, word frequency shows keyword density.

Does it count Unicode characters?

Yes. The analyzer iterates over Unicode code points, so emoji, CJK characters, and accented letters are all counted correctly.

How are words defined?

Words are matched using the regex \b\w+\b, which captures alphanumeric sequences. Punctuation and whitespace are not counted as words.
