Experience — how we tested this tool
- We tested the counter with mixed Chinese–English documents, emoji-heavy social posts and pure code snippets, then verified totals against Python and JavaScript string length functions.
- We verified that CJK punctuation (,。!?;:) is counted separately from ASCII punctuation — the most common source of confusion in mixed-language text.
- Byte count was checked against UTF-8 encoders using Chinese, Arabic, Thai and emoji input.
