I spoke about it in a previous message. There's still no WDE encoded as a control in the UCS, or as a Bidi class in the UBA, this was just an abbreviation for something that would not necessarily require a new character, but that could be simulated using RLE or LRE followed by a paragraph separator (But I know this can be tricky, because the UBA currently starts by splitting paragraphs independantly, dropping all contexts existing before them, before resolving direction levels). I don't know if what I suggested with WDE (which should also be used for mapping interlinear annotations (including ruby markup in HTML), is the same as what Deborah suggested with her NDE.. -- Philippe.
