qmake can't process project file(.pro) with UTF-8 BOM

When use MSVC compiler, If you want to compile source files with UTF-8 encoding, BOM is require. So you need to set the Text Editor behavior to add UTF-8 BOM, but qmake can't process project file(.pro) with UTF-8 BOM. It get error like this:
Unexpected UTF-8 BOM in E:/QTPro/myapp.pro
Error processing project file: E:/QTPro/myapp.pro
