Letter frequency analysis
Letter frequency analysis counts how often each letter appears — a foundational technique in cryptanalysis, linguistics, and readability research. In English, E, T, A, O, I, N are the most common letters (hence the ETAOIN SHRDLU typesetters' mnemonic). The pangram sample above — “The quick brown fox jumps over the lazy dog” — contains all 26 letters at least once, so it makes a good test for font character sets. For word-level frequency, try the Word Frequency Counter.
