You should convert widechar string to multibyte string with WideCharToMultiByte API.
Try this code: 

SHGetFolderPath =
  Win32API.new("shell32.dll","SHGetFolderPathW",["P","I","P","I","P"],"I")

WideCharToMultiByte  = 
  Win32API.new('kernel32', 'WideCharToMultiByte', 'ILPIPIPP', 'I')
path = "\0" * 256

buf="\0"*256
SHGetFolderPath.call(0,0x001A,0,0,path)
WideCharToMultiByte.call(0,0,path,-1,buf,256,0,0)
$appPath = buf.strip + "\\amaranth"
