I think this is a misunderstanding. If the encoding is properly declared,
but the characters are displayed as empty boxes, this is likely cause by the
fact that the font which is used for display just doesn't have character
glyphs at these positions.

I don't think this is a general problem at all. Just refer to the
appropriate Unicode character code, and then it's up to the browser to find
a way to display th character.
