使用 TextLayoutFormat 将嵌入字体应用于 Spark textArea 中的特殊字符
通过将 fontfamily 直接设置为 mxml 中的 textarea，字体将应用于特殊字符。但使用 tlf 并设置 fontfamily 它不适用。
style.css ::
@font-face
{
src: URL("/Assets/Fonts/GandhariUnicode-Bold.otf");
fontFamily: "GandhariUnicode-Bold";
embedAsCFF: true;
}
源代码片段 ::
textArea.textFlow.interactionManager.selectRange(beginIndex, endIndex);
var textLayoutFormat:TextLayoutFormat = getTextLayoutFormat();
textLayoutFormat.fontLookup = FontLookup.EMBEDDED_CFF;
textLayoutFormat.fontFamily ="GandhariUnicode-Bold";
textLayoutFormat.renderingMode = RenderingMode.CFF;
By setting fontfamily directly to textarea in mxml fonts get applied to special characters. But using tlf and setting fontfamily it does not apply.
style.css ::
@font-face
{
src: URL("/Assets/Fonts/GandhariUnicode-Bold.otf");
fontFamily: "GandhariUnicode-Bold";
embedAsCFF: true;
}
snippet of source code ::
textArea.textFlow.interactionManager.selectRange(beginIndex, endIndex);
var textLayoutFormat:TextLayoutFormat = getTextLayoutFormat();
textLayoutFormat.fontLookup = FontLookup.EMBEDDED_CFF;
textLayoutFormat.fontFamily ="GandhariUnicode-Bold";
textLayoutFormat.renderingMode = RenderingMode.CFF;

您是否尝试过仅设置 fontFamily 就这样？还添加正常的字体粗细定义，看看有什么变化。
Have you tried just setting the fontFamily and that's it? Add the normal font weight definition as well and see what changes.
嵌入字体的行为可能会很奇怪。我看到您使用的是粗体字体，您是否尝试在嵌入字体或/和 TextLayoutFormat 对象时将字体粗细明确设置为粗体？
另外，我发现这个线程可能有用：http://forums.adobe.com/thread/ 635711
Embedded fonts can behave strangely. I see you're using a bold font, have you tried also setting explicitely font weight to bold when embedding you font or/and on the TextLayoutFormat object?
Also, I've found this thread wich migh be useful : http://forums.adobe.com/thread/635711
