获取字体支持的字符 - 在 C# 中 [英] Get supported characters of a font - in C#

问题描述

我有一个第三方字体，支持日文字符，我需要在应用程序中使用它.每当此字体不支持字符时，就会绘制常见的矩形(默认字符").显然不是所有的日文字符都支持，因为如果我尝试绘制我们翻译办公室给我们的翻译，会有很多矩形.

I have a third party font with support for japanese characters which I need to use for an application. Whenever a character is not supported by this font, the often seen rectangle ("default character") is drawn. Obviously not all japanese characters are supported, because if I try to draw the translations that our translation office gave us, there are a lot of rectangles.

每当使用不受支持的字符时，我都需要收到通知，以便我可以更改该单个字符的字体(如 Word 所做的那样)或对此进行一些其他反应.

I need to be notified whenever a not supported character is used, so that I can change the font for this single character (like Word does it) or implement some other reaction to that.

有什么想法吗?如果我可以从 TTF 文件中提取 unicode 字符列表，那么我将能够检查该列表是否涵盖了使用的字符.但是我该怎么做呢?

Any ideas? If I could extract a list of unicode characters from the TTF file, then I would be able to check whether a used character is covered by this list. But how can I do so?

推荐答案

基于这个答案.

一定要引用PresentationCore.dll

Be sure to reference PresentationCore.dll

尝试使用此代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Media;

namespace fontChecker
{
    class Program
    {
        static void Main(string[] args)
        {
            var families = Fonts.GetFontFamilies(@"C:WINDOWSFontsArial.TTF");
            foreach (FontFamily family in families)
            {
                var typefaces = family.GetTypefaces();
                foreach (Typeface typeface in typefaces)
                {
                    GlyphTypeface glyph;
                    typeface.TryGetGlyphTypeface(out glyph);
                    IDictionary<int, ushort> characterMap = glyph.CharacterToGlyphMap;

                    foreach (KeyValuePair<int, ushort> kvp in characterMap)
                    {
                        Console.WriteLine(String.Format("{0}:{1}", kvp.Key, kvp.Value));
                    }

                }
            }
        }
    }
}
