Hi,
I don't like the idea of RLE..PDF to force paragraph direction, and it is WRONG, the Unicode BiDi Algorithm is so that puttinjg a RLE at the beginning does not set the paragraph direction to right to left, because the RLE and LRE marks are not strong characters, so the only and logical way to do this is to put a RLM. Also many implementations does not support explicit marks yet. behdad On Sat, 31 Aug 2002, Shachar Shemesh wrote: > Tzafrir Cohen wrote: > > >On Sat, 31 Aug 2002, Shachar Shemesh wrote: > > > > > > > >>Tzafrir Cohen wrote: > >> > >> > >> > >>>What about text messages? > >>> > >>>Is it possible to force directionality by beggning a document/paragraph > >>>with RLM/LRM ?
