使用 Unicode 和大字体 （.NET）

AutoCAD 支持 Unicode 字符编码标准。Unicode 字体可以包含 65,535 个字符，具有多种语言的形状。产品附带的所有 AutoCAD SHX 形状字体都支持 Unicode 字体。

某些字母表的文本文件包含数千个非 ASCII 字符。为了容纳此类文本，AutoCAD 支持一种称为“大字体”文件的特殊类型的形状定义。您可以将样式设置为同时使用常规字体文件和大字体文件。使用属性指定普通字体。使用属性指定大字体。FileNameBigFontFileName

AutoCAD 允许您指定在找不到指定字体文件时使用的备用字体。使用 FONTALT 系统变量和 Application 的 member 方法来更改使用的备用字体。SetSystemVariable
