Title problem and www ht access redirection

[napoleon]

Hi,

I don't know why but I look at my title tag for one page here is the result :

<title>Philosophie - Le domaine de la vall&eacute;e</title>

But if I look at the SERPs with site command on google here is the result :

Philosophie - Le domaine de la vallée - residence retraite rennes

Do you know why it's not the same ? I've got the same result with some pages but not all of them.

Second problem :

www ht access

here is my Ht access

AddDefaultCharset UTF-8
Options -Indexes

# blocks direct access to the XML files - they hold all the data!
<Files ~ "\.xml$">
Order allow,deny
Deny from all
Satisfy All
</Files>
<Files sitemap.xml>
Order allow,deny
Allow from all
Satisfy All
</Files>

RewriteEngine on

Options +FollowSymlinks

RewriteCond %{HTTP_HOST} ^mon-jacuzzi-gonflable.fr/$
RewriteRule ^(.*) http://www.mon-jacuzzi-gonflable.fr/$1 [QSA,L,R=301]

# Usually it RewriteBase is just '/', but
# replace it with your subdirectory path
RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ([A-Za-z0-9-]+).html index.php?id=$1 [QSA,L]

Do you know why the redirection without the www doesn't work ?

Thank you.
