[Mono-list] Support for marshalling of C# string to unmanaged wchar_t on Linux

[Kala B]

Hi,
Thanks for your suggestions.

I had actually used wsclen() in the sample code. I was
trying with strlen( and passing the string as
Charset.Auto) as well as wcslen( and passing the
string as Charset.Unicode). So, it was a copy-paste
problem. Sorry about that.

Thanks again,
Regards
Kala B.
