Fix: Support font assets with space in URL

[SuperSodaSea]

Description of change

Use encodeURI to escape URL for the constructor of FontFace.

Fixes #8910.

url with space.ttf

The url with space.ttf used in the test is an nearly empty font file generated by the following code:

import fs from 'fs';
import svg2ttf from 'svg2ttf';

const svg = `
<?xml version="1.0" standalone="no"?>
<svg xmlns="http://www.w3.org/2000/svg">
    <metadata>Test</metadata>
    <defs>
        <font id="Test">
            <font-face font-family="Test" units-per-em="1024" ascent="960" descent="-64"/>
            <missing-glyph horiz-adv-x="512" d="M 0 0 L 512 0 L 512 1024 L 0 1024"/>
            <glyph unicode="&#x20;" horiz-adv-x="512" d=""/>
        </font>
    </defs>
</svg>
`;

const ttf = svg2ttf(svg, {
    description: '-',
    url: '-',
});
fs.writeFileSync('output.ttf', ttf.buffer);
