Unlike MS.NET, Mono's p/invoke layer always uses UTF8 encoding for CharSet.Ansi
and UnmanagedType.LPStr.

If your "Function (int, int, char *, int length)" is returning non UTF8
strings, you have to marshal them manually or resort to
Mono.Unix.UnixMarshal.PtrToString*:

http://www.go-mono.com/docs/index.aspx?tlink=0@ecma%3a109%23UnixMarshal%2f

See also the docs of Mono.Unix.UnixEncoding to understand the dilemma of file
names under Unix. Just in case "Function" is returning file names...
