What is MSVC’s default execution character set?

According to MSVC’s documentation, I can use the /execution-charset option to change which execution character set a program uses. Let’s say that I don’t use the /execution-charset option. What execution character set will MSVC use by default?

The documentation for /execution-charset says:

By default, Visual Studio detects a byte-order mark to determine if the source file is in an encoded Unicode format, for example, UTF-16 or UTF-8. If no byte-order mark is found, it assumes that the source file is encoded in the current user code page, unless you used the /source-charset or /utf-8 option to specify a character set name or code page. Visual Studio allows you to save your C++ source code in any of several character encodings. For information about source and execution character sets, see Character sets in the language documentation.

When I first read it, I thought that that paragraph answered my question, but after rereading it, I now think that that paragraph is a copy-paste error. That paragraph talks about the character encoding of source code files, but that’s different than the execution character set. If I wanted to adjust the character encoding of the source code files, then I would use the /source-charset option.
