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;
