our database and website pages only support Latin1

As Corion explained, what you've asked for can't be done since the set of possible characters in UTF8 is much bigger than the set of possible characters in Latin-1.

HTML does allow you to represent any character regardless of the encoding. For example, the character 'Ā' is not in Latin-1 but you can include it in HTML with Ā. However that would only work if you stored HTML encoded text in your database - which would be an odd thing to do.

By far the best answer is to update your database and web pages to UTF8.
