I suspect that the text you pasted from PageMaker is not encoded in a Unicode-compatible font, because Adobe PageMaker does not currently support it (cf. https://groups.google.com/forum/#!topic/technical-hindi/xtCKJmr4aBw).
You can test this out by pasting the sample Hindi text from this site: http://rishida.net/scripts/samples/hindi into your Moodle. If it displays correctly, then both your Moodle server and your current PC client web browser are configured correctly, and PageMaker is definitely the problem.
If it doesn't, your Moodle server could be correct, but your client PC and/or web browser might not be configured properly.
