weird characters displayed in editor

[testsetup]

The editor is taking hypens and changing them to: –
It saves them like this as well and overwrites the site.

The site is designed in Expresion Web Desinger and here is the html it is changing:

Code:

<span class="greentext">Paths &amp; Tracks</span> – a ball lying

In the editor it is showing code of:

Code:

><span class="greentext">Paths &amp; Tracks</span> &acirc;&euro;&ldquo; a ball lying

However in the sentence above this in the site where the hypen is not preceded by a space it interprets it correctly:

Code:

<span class="greentext">Manure </span>- if a ball lies

It also did this with a page that had an apostrophe in when designed and freshly uploaded by EWD:

Code:

Town’s

- had a combination of funny characters in its place.
I edited it using the editor, replacing the characters with an apostrophe, saved it and it shows ok now.

However it has replaced the apostrophe in the html with:

Code:

Town&#39;s

I really do not want to have to correct every page in the site made with EWD before handing over to the client if possible.

Does anyone know the fix please?

I think this has to do with the character encoding you have specified for the site.
