add custom font simsun in jsPDF - unicode

Question

I need export pdf with chinese letters, and write code as below link says:
Custom font faces in jsPDF?
and my code:
css:
#font-face {
font-family: SimSun;
font-weight: normal;
font-style: normal;
src: url("./simsun.ttc");
}
body{
font-family: 'SimSun';
}
js:
pdf.addFont('SimSun', 'SimSun', 'normal','StandardEncoding');
pdf.setFont('SimSun');
pdf.text(20, 20, '西溪园区 5号楼 1F');
pdf.save('TestSVG.pdf');
And as someone said that, i have confirmed that addFont is public:
API.addFont = function(postScriptName, fontName, fontStyle) {
addFont(postScriptName, fontName, fontStyle, 'StandardEncoding');
};
And i also find the postScriptName of 'Simsun' is SimSun.

Can somebody tell me why?

You're trying to load a truetype collection, not a truetype font. Current versions of CSS do not support font collections, so unpack your collection and then load the individual fonts, instead.
#font-face {
font-family: SimSun;
font-weight: normal;
font-style: normal;
src: url("./simsunregular.ttf");
}
#font-face {
font-family: SimSun;
font-weight: bold;
font-style: normal;
src: url("./simsunbold.ttf");
}
...etc...
body{
font-family: 'SimSun';
}
