Syntax
FString PayloadKey
Remarks
A dynamically sizeable string. When dealing with UTF-8 literals, the following advice is recommended:
- Do not use the u8"..." prefix (gives the wrong array type until C++20).
- Use UTF8TEXT("...") for array literals (type is const UTF8CHAR[n]).
- Use UTF8TEXTVIEW("...") for string view literals (type is FUtf8StringView).
- Use or escape sequences rather than to specify Unicode code points.
