+  A temparaty function that returns the size of a Null-terminated Unicode
+  string in bytes, including the Null terminator.
+
+  This function returns the size, in bytes, of the Null-terminated Unicode
+  string specified by String. It duplicates the functionality of StrSize()
+  in MDE library, but avoids using PCD, because IPF currently cannot convert
+  address of global variable for runtime.
+
+  If String is NULL, then ASSERT().
+  If String is not aligned on a 16-bit boundary, then ASSERT().
+
+  @param  String  Pointer to a Null-terminated Unicode string.
+
+  @return The size of String.
