Specifies both the source character set and the execution character set as UTF-8.
/utf-8
You can use the /utf-8 option to specify both the source and execution character sets as encoded by using UTF-8. It's equivalent to specifying /source-charset:utf-8 /execution-charset:utf-8 on the command line. Any of these options also enables the /validate-charset option by default. For a list of supported code page identifiers and character set names, see Code Page Identifiers.
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've specified a code page by using /utf-8 or the /source-charset option. 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.
