QT 4.x has made a lot of progress for Unicode rendering in the Scribe engine : http://doc.trolltech.com/4.0/qt4-scribe.html I've watched a demonstration by the developer Lars Knoll and I was quite impressed. It handles not only RTL language but also ligatures in arabic. For example, if you cut part of a word and break a ligature, it will repaint it correctly in the clipboard. It also works with some Indic languages which are more complex than Arabic or Hebrew. It manages the cursor correctly if for example you insert an English word in an Hebrew paragraph. Can't we leverage Trolltech's work in LyX ? Lars Knoll told us that it was a very difficult library to program because of the multiple subtle differences between languages. In general, trusting Norwegian software engineers named Lars is a good thing ;-) Cheers, Charles -- http://www.kde-france.org
