运行时选择exSpriteFont物体抛出异常

[xw0]

1. 运行程序
2. 动态添加一个包含有exSpriteFont的GameObject
3. 打开Scene View
4. 在Hierarchy View里选择刚才创建的GameObject
5. 无限抛出异常

我这边使用beta3及beta4版本进行测试，均未能复现，麻烦你用beta4再测看看。

update到beta4，问题依然存在。而且以前在游戏里能看到的exSpriteFont现在都看不到了。

当选择exSpriteFont并切换到Scene View时，有一个log和两个error不停的重复显示：

The targets array should not be used inside OnSceneGUI or OnPreviewGUI. Use the single target property instead. UnityEditor.DockArea:OnGUI()

以前还有一个很奇怪的和exSpriteFont有关的bug。我用的字体里包括x0123456789十个字符。但是如果用font.text = "x01"，这个font显示不出来。但用font.text = "001"又可以。后来的walkaround是先把它设置成001，然后再改成x01，就能显示了。但beta4里好像spritefonts怎么都不显示。感觉这些问题应该都有相关性，就一并说一声了。

谢了！已经重现并修复了Scene View里面的报错，同时修复了你后面说的显示异常的bug。
