Pangram Checker
Check whether text contains every ASCII letter a through z, case-insensitively.
Description
Check whether text contains every ASCII letter from a through z.
A pangram uses every letter of an alphabet. This checker follows the 26-letter English ASCII definition used in typography samples, keyboard exercises, and word games.
When to use Pangram Checker
- Verify an English pangram
- Check a keyboard sample phrase
- Test complete a-to-z coverage
How the calculation works
ASCII letters are extracted case-insensitively and placed in a set. The answer is true when that set has 26 members; duplicates and punctuation do not matter.
Interpreting the result
True means each letter appears at least once, not exactly once. Use letter frequencies to identify missing letters or test a perfect pangram.
Important limitations
- Only the ASCII English alphabet is considered.
- Missing letters are not listed directly.
