Remove BOM from page output via web.config

Question

Currently our pages are being output with the Unicode BOM.

I have found one way of removing this by adding the following to my masterpage's OnInit.

Response.ContentEncoding =  System.Text.UTF8Encoding(false);

Where the false being passed to the UTF8Encoding constructor disables the BOM.

This works fine, but I'd prefer to set this in the web.config rather than relying on it being in the OnInit hierarchy of any given page.

The globalization element has a responseEncoding attribute which takes a string representation of a valid endcoding. e.g.

<globalization
    responseEncoding="utf-8"
    ... />

Is there any way of representing "utf-8 without BOM" as a string which could be used as the value for responseEncoding in the web.config?
