However, I strongly disagree with Rüdiger Timm's `Even RTL languages don't use RTL for math` !! That's completely wrong, many countries still uses Arabic letters in math formula. People forgot that Math formula could be written in other languages to teach kids in school basic geometry rules. For example, how can somebody type this 5th grade formula without inducing kids in error: مساحة شبه المنحرف = (القاعدة الكبرى + القاعدة الصغرى) × الارتفاع ÷ 2 ( Trapezoid Area = (smaller side + bigger side) × height ÷ 2 ) Making exercises or lessons for kids in school would be impractical in LibreOffice :( I hope in the future that at least the text direction control characters will be supported in math formula output..</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
