Displaying Chinese ideographs in svg page with Javascript and unicode

[Fulio Pen]

Hello,

Please open the following svg page:

http://www.pinyinology.com/test/tree2.svg

I want to replace the English words in above page with corresponding
ideographic Chinese characters. Directly entering Chinese characters
into the svg file with Chinese IME doesn't work, because the
characters will not show on the IE and Firefox browsers. So the
characters must be displayed with Javascript and unicode, like what is
done in the following svg page:

http://www.pinyinology.com/test/characters.svg

Four Chinese characters will displayed in the svg page. Their unicode
are listed in the following page:

http://www.pinyinology.com/test/span3.html

Please note that each character will appear at four different
locations in the page. Also, the English words should be removed Only
the Chinese character are present in the page.

Thanks for your expertise and help.
