Tilde ~ does not appear correctly in posts

I have just posted a post which includes a tilde but it appears as ~. Why?

˜ or ~ Are the same according to Wikipedia. I believe it depends upon the Font used by your Browser and System.

Beardedragon: I assumed it was a forum issue because a tilde appears ( in Firefox and Opera) correctly on the forum index page for me but incorrectly as "-" in the post. In your post which quotes my original post the tilde appears correctly!
