itextsharp library instead of PdfSharp and rtl support

i think for nop that support multilaguage is important to support
1.rtl and unicode language full for example in pdf created files i suppose to use itextsharp
2.create one property with the name IsRTL in language table to inject  RTL css to pages.
3.support hijri or persian calender i suppose to use jquery calender ui instead of telerik calender

+1 request.
itexhSharp to support rtl languages and jquery ui calendar to support persian date.

also some changes that might help people with persian language:

in NopDatePicker the code that fills the dropdownlist should change like this:

for (int i = this.LastYear, j = this.LastYearByCulture; i >= this.FirstYear; i--, j--)
            {
                ListItem tempItem = new ListItem();
                tempItem.Text = j.ToString();
                tempItem.Value = i.ToString();
                lstYears.Items.Add(tempItem);
            }

and a new property is needed:

public int LastYearByCulture

which by "get" should return:

Thread.CurrentThread.CurrentCulture.Calendar.GetYear(DateTime.Now);

which also needs assigning the PersianCalendar to persian CultureInfo in SetCulture method, the calendar is not the default calendar unfortunately.

i know how can i impelement it but i request to add this features by default.
do you have iranian bank payments?

fix for it
change pdfservice page and add this line for each new table


const string regex_match_arabic_hebrew = @"[\u0600-\u06FF,\u0590-\u05FF]+";
    if (Regex.IsMatch("מה קורה", regex_match_arabic_hebrew, RegexOptions.IgnoreCase))
    {
        table.RunDirection = PdfWriter.RUN_DIRECTION_RTL;
    }
