How Character Counter works
How does the character counter work?
It reads the text length directly, which counts UTF-16 code units in JavaScript, then derives the other stats with simple pattern matching: whitespace is stripped for the "no spaces" figure, [a-zA-Z] matches count letters, [0-9] matches count digits, and literal space characters are tallied separately from tabs or line breaks. The byte count uses the browser's TextEncoder to measure how many UTF-8 bytes the same text would occupy.
When is this tool useful?
It is built for places with strict character limits - social posts, SMS messages, meta descriptions, or form fields that cap input length. The UTF-8 byte count matters specifically when a system enforces limits in bytes rather than characters, which diverges once you type accented letters or non-Latin scripts.
Why does the letter count look low for non-English text?
The letters figure only matches the basic Latin alphabet, so accented characters, Cyrillic, Chinese, Arabic, and similar scripts will not register as "letters" even though they count toward the total characters and bytes. As with the other counting tools here, every calculation happens locally rather than on a server.
