How to use Mac input sources in Parallels?

Hi,

I have just bought Parellels since I am using a language-program for my work that only works on PC. I had hoped that I could use the MAC input source in Parellels. This seems to work form some languages, but not for Hindi (the language I work with). Does anyone know how to make you apple input sources work in Parallels, or even to download apple input sources to a PC?

Kind regards,
David
