This line is incorrect. You are telling the compiler to interpret 
an UTF-8 byte stream as if it was UTF-16.

This line is correct. If you are getting an UTF exception, that 
means that your terminal is not configured to use UTF-8. Your 
accent characters are probably encoded as an ASCII encoding, not 
UTF-8.

I see you're posting from a Windows machine. On Windows, to 
switch the terminal to UTF-8, type this command first:

chcp 65001

You can do this programmatically in your D program using 
SetConsoleCP and SetConsoleOutputCP. Note, though, that doing so 
can affect execution of your program from Windows batch files.
