That is the Hebrew readers are used to it (i.e. in HTML pages and printed text - newspapers and articles). Eli has explained the difficulties to do it with the current Emacs display engine. Emacs has some properties (text overlays is a major example) that make it even more difficult. Until a better bidi display engine is in place, I'll write my own elisp code to do the re-flow on long mixed lines, so the actual work will be acceptable. -- Ehud Karni Tel: +972-3-7966-561 /"\ Mivtach - Simon Fax: +972-3-7976-561 \ / ASCII Ribbon Campaign Insurance agencies (USA) voice mail and X Against HTML Mail http://www.mvs.co.il FAX: 1-815-5509341 / \ GnuPG: 98EA398D Better Safe Than Sorry
