RichTextBox.RTF设置程序抛出System.ArgumentException.文件格式在Windows版本1803中无效 [英] RichTextBox.RTF setter throwing System.ArgumentException. File format is not valid in Windows version 1803

问题描述

模拟以下情况以重现崩溃:

The following scenario is simulated to reproduce the crash:

1. 启用 Beta:Unicode UTF-8以支持全球语言( 启用开始=>区域和语言设置=>相关设置-> 附加日期，时间和时间区域设置=>区域->更改日期， 时间或数字格式=>选择管理"选项卡=>单击 更改系统区域设置.
2. 检查Beta:针对全球语言支持的Unicode UTF-8复选框
3. 重新启动系统

4. 在Windows窗体中，Application =>添加一个窗体，RichTextBox，Button和 标签OnButtonClick =>在行下方添加

1. Enable Beta: unicode UTF-8 for world wide language support (To enable Start=> Region & Language settings => Related settings -> Additional date, time & regional settings => Region -> Change date, time or number formats => select Administrative tab => Click on Change System Locale.
2. Check Beta: unicode UTF-8 for world wide language support checkbox
3. Restart the system

4. In Windows forms Application => Add a form, RichTextBox, Button and a label OnButtonClick => add below lines

richTextBox1.SelectAll();
richTextBox1.Rtf = richTextBox1.SelectedRtf; //Leads Crash System.ArgumentException: File format is not valid.
label1.Text = "RichTextBox1.Rtf = " + richTextBox1.Rtf;

如果我们取消选中 Beta:全球语言的Unicode UTF-8 支持，然后重新启动系统就没有问题.

If we UnCheck Beta: unicode UTF-8 for world wide language support, and restart the system there was no issue.
