Weird Code and trying edit old body data but opens erased

I'm having two issues after upgrading my site to the latest version from 1.37 to 1.5.1.

When I copy from crimson editor or notepad I get these strange symbols **Â **to pop up through out the body.

example
http://www.sullivanvitamins.com/index.php?main_page=product_info&cPath=200_140&products_id=6913

Also when I click to edit a product's information that is display on the public view such as product description it is empty on the admin side.

What is causing these issues?

Set your 1.5.1 to use the old CHARSET you were using in 1.3.x:
http://www.zen-cart.com/content.php?313-should-i-convert-my-store-from-iso-8859-1-to-utf8

Sorry but what is the exact folder these are located in as there is more than one.

```php
Do I need to convert to UTF-8?
If your site IS RUNNING or you have UPGRADED FROM an older version of Zen Cart where your language files are/were set to iso-8859-1, and you don't have any specific need for extended-character multibyte support (for example your store is only in english and only english-speaking customers visit your store), then you may find it best to keep your site in iso-8859-1 (aka "latin1") mode instead of converting to UTF8.

To do this, you'll need to fix BOTH your admin and non-admin files:
Edit your upgraded english.php file to use the old CHARSET and setlocale settings (SEE YOUR OLD english.php FILE CONTENTS).
That is, KEEP the old references to iso-8859-1 INSTEAD of utf-8.
... AND ...Also edit your two configure.php files to set DB_CHARSET to 'latin1' instead of 'utf8'
(add the line if it doesn't exist):
define('DB_CHARSET', 'latin1');

Sorry for the bump but it looks like the admin english.php was causing the problems as the two english.php I opened up in public folders were still iso-8859-1.
