(HTML5) cannot display Chinese characters when using UTF-8
===

I am trying to display some Chinese characters on my web page using HTML5.

    var canvas = document.getElementById('canvas');
    var context = canvas.getContext('2d');

    // ...
    
    context.fillText('中文', 0, 0);

    context.fill();


And I have checked several questions here and added the following in the header.

    <meta charset="UTF-8" />

I tried in Firefox 14, and it shows `????` on the screen. While I realized that, my browser setting of character encoding is `UTF-8`. When I changed it to 'Big5`, it displays well.

My question is, can the script allow browser to display Chinese (and perhaps all other non-English) characters properly without changing to the specific character encoding? i.e. keeping the setting as `UTF-8` and then nothing deal with the user's browsers furthermore because I want my page to display more than one language.

Thanks.
