Custom e-mail link

I’m trying to get a custom email link to work on all of my posts. Basically I just want text that shows on each post that links to an email.

This is the code I included which displays correctly:
<a href="mailto:?subject=<?php rawurlencode (the_title()); ?>&body=<?php rawurlencode (the_permalink()); ?>">Email This Post</a>

The only problem I have is that if there happens to be an apostrophe in the title it doesn’t work.

What’s displays as “What’s”

I’m also worried that maybe other characters are going to be messed up. What’s weird is that if I use a plugin like Sociable, then it displays correctly so clearly there is a right way to do it. I just want text instead of graphic.

Any help on what I’m missing?
