I had to change the strategy like this
var t = PdfTextExtractor.GetTextFromPage(reader, i, new LocationTextExtractionStrategy());
var te = Convert(t);
and this function to reverse the Arabic words and keep the English
private string Convert(string source)
{
string arabicWord = string.Empty;
StringBuilder sbDestination = new StringBuilder();
foreach (var ch in source)
{
if (IsArabic(ch))
arabicWord += ch;
else
{
if (arabicWord != string.Empty)
sbDestination.Append(Reverse(arabicWord));
sbDestination.Append(ch);
arabicWord = string.Empty;
}
}
// if the last word was arabic
if (arabicWord != string.Empty)
sbDestination.Append(Reverse(arabicWord));
return sbDestination.ToString();
}
private bool IsArabic(char character)
{
if (character >= 0x600 && character <= 0x6ff)
return true;
if (character >= 0x750 && character <= 0x77f)
return true;
if (character >= 0xfb50 && character <= 0xfc3f)
return true;
if (character >= 0xfe70 && character <= 0xfefc)
return true;
return false;
}
// Reverse the characters of string
string Reverse(string source)
{
return new string(source.ToCharArray().Reverse().ToArray());
}
