用什么字体，如果一个Unicode字符未在选定字体（宋体）发现了什么？ [英] What font is used if a Unicode-character is not found in the selected font (Tahoma)?

问题描述

我写了使用宋体作为字体显示unicode字符串，其工作罚款WPF用户控件。不过，我已经注意到，一些东亚字符实际上是缺少宋体，即该字体不支持所有常见的Unicode字符。

I have written a WPF user control that uses Tahoma as a font to display unicode strings, which works fine. However, I have noticed that some eastern asian characters are actually missing in Tahoma, i.e. this font does not support all common Unicode characters.

然而，当我显示的字符串包含一些东亚的信件，我料想在Tahoma.ttf丢失，字符显示正常，无论如何，而不是一个黑色的矩形，我有望获得失踪的Unicode字符。

However, when I display a string that contains some east asian letters, that I suppose are missing in Tahoma.ttf, the character is displayed correctly anyway, instead of a black rectangle that I expected to get for the missing unicode character.

于是出于好奇：有没有回退机制，IE浏览器的Windows 7或C＃WPF从后备字体替换缺少的人物？任何人都可以请解释一下这是如何准确地工作，和字体实际用作allback？

So out of curiosity: is there any fallback mechanism, i.e. does Windows 7 or C# WPF replace the missing characters from a fallback font? Can anybody please explain how exactly this is working, and which font is actually used as a allback?

推荐答案
