Enabling rails page caching causes the http header path to disappear

I need the encoding for utf-8, which is apparently the default. I recently turned on page caching for multiple static pages:

caches_page :about

Caching works fine, and I see the corresponding about.html and contact.html pages generated in my / public folder, except when the page is displayed, it is no longer in utf-8.

After I searched several times, I tried to look at the http headers with wget, before and after caching:

first time:

$wget --server-response http://localhost:3000/about

HTTP request sent, awaiting response... 
 1 HTTP/1.1 200 OK
 2 X-Ua-Compatible: IE=Edge
 3 Etag: "f7b0b4dea015140f3b5ad90c3a392bef"
 4 Connection: Keep-Alive
 5 Content-Type: text/html; charset=utf-8
 6 Date: Sun, 12 Jun 2011 03:44:22 GMT
 7 Server: WEBrick/1.3.1 (Ruby/1.8.7/2009-06-12)
 8 X-Runtime: 0.235347
 9 Content-Length: 5520
10 Cache-Control: max-age=0, private, must-revalidate

cached:

$wget --server-response http://localhost:3000/about

Resolving localhost... 127.0.0.1
Connecting to localhost[127.0.0.1]:3000... connected.
HTTP request sent, awaiting response...

 6 Server: WEBrick/1.3.1 (Ruby/1.8.7/2009-06-12)
 7 Content-Length: 5783

as a result, the page is displayed in ISO-8859-1, and I get a bunch of garbled text. Does anyone know how I can prevent this unwanted result? Thank.
