Elika, I am confused by last sentence of next-to-last paragraph of section 5.0: " Scripts with a native vertical orientation have an intrinsic bi-orientational transform, which orients them correctly in vertical text: most CJK (Chinese/Japanese/Korean) characters translate, that is, they are always upright. **Characters from other scripts, such as Mongolian, rotate.** " 5. Introduction to Vertical Text Layout https://drafts.csswg.org/css-writing-modes-3/#intro-text-layout https://www.w3.org/TR/css-writing-modes-3/#intro-text-layout If Mongolian is known to be a vertical-only, vertical native orientation script, then I think the sentence between the pair of ** should be removed, otherwise corrected. - - - - - - - http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/s51-text-orientation-Mongolian-upright-002.xht http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/s51-text-orientation-Mongolian-upright-002-ref.xht Gérard
