Hi
Thanks for bringing that to attention. At the moment rtl is not supported.
I would not rely on a regex to determine the text direction after all
perhaps some one intend to display it in the other run direction?
I would opt for using CSS to set the run direction. Just like in html
{
direction:rtl;
}
the encoding should be settable in the same way, we can add an xmlworker
specific css property for that. Forcing .CP1252 is not a good idea,
that's right.
Thanks for the idea
ps: please don't hijack other threads, write a new message for a new
topic, I almost mist this mail.

Hello,
In iTextSharp.tool.xml.css.apply.ChunkCssApplier class, String
encoding is hardcoded to BaseFont.CP1252.
It's easy to detect right to left languages data:
static readonly Regex MatchArabicHebrew = new
Regex(@"[\u0600-\u06FF,\u0590-\u05FF]+", RegexOptions.IgnoreCase |
RegexOptions.Compiled);
public static bool IsRtl(string data)
{
if (string.IsNullOrEmpty(data)) return false;
return MatchArabicHebrew.IsMatch(data);
}
And then we can improve Apply method of ChunkCssApplier class for
instance:
public Chunk Apply(Chunk c, Tag t)
{
String fontName = null;
String encoding = BaseFont.CP1252;
if (IsRtl(c.Content)) encoding = BaseFont.IDENTITY_H;
Also run_direction should be set for PdfPCell and other similar
elements to RTL.
Ex. iTextSharp.tool.xml.html.table.TableData class
public override IList<IElement> End(IWorkerContext ctx, Tag tag,
IList<IElement> currentContent) {
HtmlCell cell = new HtmlCell();
IList<IElement> l = new List<IElement>(1);
foreach (IElement e in currentContent) {
if(e is Chunk)
if (IsRtl(((Chunk)e).Content))
{
cell.RunDirection = PdfWriter.RUN_DIRECTION_RTL;
}
