Thank You Isaac 4 the quick answer.
While following your instructions I just get stucked at Step 3

1. Go to: Control Panel » Languages
2. Click on the "Language Editor" tab.
3. In the "Search String" field, type "UTF-8" and press "Go" button.

The result is a Blanc page, even a view in the source text is not really informative, there is nothing written?

Sorry for the mess...
