如何確定哪些字體包含特定字符？

Question

給定一個特定的Unicode字符，比方說，我如何遍歷系統中安裝的所有字體並列出包含此字符的字形的字體？

我已經在.NET 4.0上測試過了，您需要添加對PresentationCore的引用以獲取字體&字體類型的工作。另請檢查Fonts.GetFontFamilies overloads。

using System; 
using System.Collections; 
using System.Collections.Generic; 
using System.Windows.Markup; 
using System.Windows.Media; 

class Program 
{ 
    public static void Main(String[] args) 
    { 
     PrintFamiliesSupprotingChar('a'); 
     Console.ReadLine(); 
     PrintFamiliesSupprotingChar('â'); 
     Console.ReadLine(); 
     PrintFamiliesSupprotingChar('嗎'); 
     Console.ReadLine(); 
    } 

    private static void PrintFamiliesSupprotingChar(char characterToCheck) 
    { 
     int count = 0; 
     ICollection<FontFamily> fontFamilies = Fonts.GetFontFamilies(@"C:\Windows\Fonts\"); 
     ushort glyphIndex; 
     int unicodeValue = Convert.ToUInt16(characterToCheck); 
     GlyphTypeface glyph; 
     string familyName; 

     foreach (FontFamily family in fontFamilies) 
     { 
      var typefaces = family.GetTypefaces(); 
      foreach (Typeface typeface in typefaces) 
      { 
       typeface.TryGetGlyphTypeface(out glyph); 
       if (glyph != null && glyph.CharacterToGlyphMap.TryGetValue(unicodeValue, out glyphIndex)) 
       { 
        family.FamilyNames.TryGetValue(XmlLanguage.GetLanguage("en-us"), out familyName); 
        Console.WriteLine(familyName + " Supports "); 
        count++; 
        break; 
       } 
      } 
     } 
     Console.WriteLine(); 
     Console.WriteLine("Total {0} fonts support {1}", count, characterToCheck); 
    } 
}
