QT_NO_UTF8_SOURCE
防止强制将源文件视为 UTF-8 格式（适用于 Windows）。
该属性自 Qt 6.0 起引入。
在使用某些 Windows 编译器进行构建时，链接到 Qt 库的目标会使用标志强制编译器将其源文件视为 UTF-8。目前，此功能已针对 Visual Studio 和 Intel 编译器实现。您可以通过将该属性设置为 `TRUE`，按目标逐个禁用此行为：
set_property(TARGET target_name PROPERTY QT_NO_UTF8_SOURCE TRUE)注意：这 不会改变QString 等类的运行时行为（其来自const char * 的构造函数需要正确编码的UTF-8输入）。请使用QT_NO_CAST_FROM_ASCII 和QT_RESTRICTED_CAST_FROM_ASCII 宏来帮助识别此类代码。
另请参阅 qt_disable_unicode_defines()和qt_allow_non_utf8_sources()。
