How to use the hexo-util.encodeURL function in hexo-util

it('url - IDN', () => {
    const ctx = {
      page: {},
      config: hexo.config,
      is_post: isPost,
      url: 'https://foô.com/bár'
    };

    const result = openGraph.call(ctx);

    result.should.contain(meta({property: 'og:url', content: encodeURL(ctx.url)}));
  });

const checkURL = function(url, root) {
      hexo.config.url = url;
      hexo.config.root = root;

      const feedCfg = hexo.config.feed;
      const result = generator(locals, feedCfg.type, feedCfg.path);
      const $ = cheerio.load(result.data);

      if (url[url.length - 1] !== '/') url += '/';
      const punyIDN = encodeURL(url);
      $('feed>id').text().should.eql(punyIDN);
    };

const urlA = '/foo/bár.jpg';
      const urlB = 'http://fóo.com/bar.jpg';

      const body = [
        `![](${urlA})`,
        `![](${urlB})`
      ].join('\n');

      const r = require('../lib/renderer').bind(hexo);

      const result = await r({text: body});

      result.should.eql([
        `<p><img data-src="${encodeURL(urlA)}">`,
        `<img data-src="${encodeURL(urlB)}"></p>\n`
      ].join('\n'));
    });
  });
