Related to https://github.com/mozilla/pdf.js/issues/7696 Which version of Adobe-Japan1-UCS2.bcmap do you have?

Which version of Adobe-Japan1-UCS2.bcmap do you have?

I don' t know the version of bcmap files. I had not installed bcmap files. I had installed vue-pdf-app only.

Do I need to install other modules like pdfjs-dist separately to get bcmap files installed? If so, how can I specify the url path of the bcmap files?

经过查看源码后，可以通过覆盖方法的方式解决此问题

<VuePdfApp
  :pdf="pdfSrc"
  @after-created="afterCreatedHandler"
/>
export default {
  methods: {
    afterCreatedHandler(app) {
      const oldOpen = app.open.bind(app)
      app.open = function (file, args = {}) {
        return oldOpen(file, {
          ...args,
          cMapUrl: 'https://cdn.jsdelivr.net/npm/pdfjs-dist@2.2.228/cmaps/',
          cMapPacked: true,
        })
      }
    }
  }
}

Instead of using the CDN link , I have downloaded the bcmap file in my local. I need to use these downloaded bcmap files.
