Tried to save an application form from the internet, but doesn't open in word? HELP!?

[Bad girl gone good :)]

I urgently need this application form,
However, when I click the save button at the bottom of the page, and click the saved version from my desktop, the words go all weird. What I mean by that, is some options like Chinese etc comes up and when I click on any option, it is just pages of jumble of letters and symbols.

I hope that makes sense, how can I save this form on my desktop and then fill out without having troubles with it!

This is the form. http://www.magentastar.co.uk/documents/O...n-Form.pdf

Thanks for all your help! If there is any questions, just check back at this question I will add some more info.
