I’m having trouble merging document, accented text is getting wrong charset.

```javascript
const xfdf = await this.annotManager.exportAnnotations({links: false, widgets: false});
    const fileData = await this.docViewer.getDocument().getFileData({});
    const blob = new Blob([fileData], {type: 'application/pdf'});

    const data = new FormData();
    data.append('xfdf', xfdf);
    data.append('file', blob);
    data.append('license', 'xxxxxxxxxx');

    // Process the file
    const response = await fetch('https://api.pdfjs.express/xfdf/merge', {
      method: 'post',
      body: data
    }).then(resp => resp.json());

```
