While building for a specific platform, error C4828 appears.
This error is >> The file contains a character starting at offset 0xvalue that is illegal in the current source character set (codepage number).
Of course, this can be solved by saving the source code in UTF-8 format, but it cannot be adopted because problems arise during the process of merging with the existing SVN.
I added the command line below to BuildTool, but it was the same.
"/source-charset:utf-8 "
“/execution-charset:utf-8”
Is there any way?
