A text-rewriting tool encountered significant issues when expanding its language support beyond English, particularly with German, Japanese, French, Chinese, Arabic, and Hebrew. The tool's English-centric rules for sentence length, punctuation, formality, and vocabulary proved ineffective or even detrimental in other languages. For instance, shortening sentences that are naturally longer in German or misinterpreting punctuation conventions in Chinese led to unnatural-sounding text. The developers realized that linguistic nuances like formality (e.g., tu vs. vous in French) and script directionality (Right-to-Left for Arabic and Hebrew) require language-specific handling rather than direct translation of English rules. They developed a per-language checker to enforce these linguistic rules, emphasizing the need for native speakers to review the output. AI
