Script Character ↔ Word Counter
Analyze typography metrics, spaces, and punctuations. Project target layouts between Latin and CJK scripts.
• Chinese/Japanese (CJK): Double-byte characters, single-char words. 1 word usually averages 1.5 characters.
• English (Latin): Multi-letter words separated by whitespace. Standard average is 5 letters + 1 space per word.
