Good to know

  • Shift_JIS, EUC-JP, and JIS byte counts are practical estimates for common Japanese text.

FAQ

Does it work with Japanese text?
Yes. Character, line, full-width, UTF-8 byte, and practical legacy Japanese byte estimates work with Japanese and other Unicode text.
Are word counts exact for every language?
Word counts are useful for space-separated languages and approximate for languages without spaces.
Are Shift_JIS, EUC-JP, and JIS bytes exact?
They are practical estimates for common Japanese text. Emoji and characters outside older encodings are counted separately.
How is 400-character manuscript paper estimated?
It divides non-space characters by 400 and rounds up to estimate how many sheets are needed.
