使用itextsharp在c＃中提取阿拉伯語文本

Question

我有這段代碼，我正在使用它來獲取PDF文本。這對使用英文的PDF格式非常有用，但是當我嘗試用阿拉伯語提取文本時，它會顯示出類似這樣的內容。

「）+ N 9 N < +，+）+ $＃$ + $ F％9 & < $：;」。

using (PdfReader reader = new PdfReader(path)) 
{ 
    ITextExtractionStrategy strategy = new SimpleTextExtractionStrategy(); 
    String text = ""; 
    for (int i = 1; i <= reader.NumberOfPages; i++) 
    { 
     text = PdfTextExtractor.GetTextFromPage(reader, i,strategy); 
    } 

Answer 1

我不得不改變這樣

var t = PdfTextExtractor.GetTextFromPage(reader, i, new LocationTextExtractionStrategy()); 
var te = Convert(t); 

戰略，此功能可扭轉阿拉伯語單詞和保持英語

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()); 
     }
