Right now, it's exclusively ASCII, so no questions asked. Furthermore, XML processors are more used to have entities rather than exotic characters; similarly, MathType uses this kind of entities when exporting in MathML. When users display the XML document, they must use a font that has all the needed characters, which is far from guaranteed. > Günter > > -- > lyx-devel mailing list > lyx-devel@lists.lyx.org > http://lists.lyx.org/mailman/listinfo/lyx-devel >
