[Mono-dev] UnmanagedType.LPWStr and Big-Endian Unicode

[Kornél Pál]

Hi,

On big-endian machines everything is big-endian, including P/Invoke. In fact 
there is no need to big-endian conversion because managed strings are 
big-endian on big-endian machines. They are converted when they are read 
from your assembly files.

Only things documented to be little-endian are little-endian on big-endian 
machines.

For more information have a look at
