Which Collation Format Should I Use?

Which collation format should I use?

 SQL_Latin1_General_CI_AS,
 SQL_Latin1_General_CP1_CI_AS, or
 Latin1_General_CI_AS

I noticed that my development server has a different collation setting to the production server.

development. SQL_Latin1_General_CP1_CI_AS
production.  Latin1_General_CI_AS

Both these servers are SQL Server 2005 Express and I typically use varchar or text fields for storing the data.

I've been told that the difference between them is that the former uses code page 1252, as specified here:
http://www.microsoft.com/globaldev/reference/sbcs/1252.mspx

However when I compare that to, say, the page of symbols one gets using the 'Insert, Symbol' command via microsoft word I find quite a disagreement. It also differs from the 'View, Clip Library' list provided by TextPad.

The data in my database uses non-ASCII characters (or extended ASCII, if you prefer). The administrators of my CMS will sometimes copy and paste or write European spellings for company names etc. When they do that they're likely to resort to Word's Insert Symbol command. When I get this data and show it on a web page I want to specify utf-8 endcoding.

Which of these SQL server collations should I be using. I suspect that I should be using SQL_Latin1_General_CI_AS.  Essentially, I want the charater as seen in the textbox of the CMS to look identical to that displayed on a web page which has the following meta tag set: <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

The aforementioned CMS administrators are entering data on Windows XP PCs running asp.net. They may get the accented characters from several different sources (MS Word Insert Symbol or cut and paste from a web page), but they can agree with me that the symbol should display in the text box of the CMS identically to that on the web site.

Can someone put me right on this?
