⚠️ Important change

  • Improved word counting for multiple languages, including ones without spaces. Previously, words were identified using spaces and punctuation, causing entire sentences in languages such as Japanese and Chinese to be counted as a single word. WProofreader now uses ICU-based segmentation to count morphemes for these languages, providing more accurate word counts and language statistics. For example, わかんない is now counted as 3 morphemes (わか / ん / ない), rather than 1.
