比如：当文件名存在 `|` 或空格

引起问题的代码

可能的修正：

```js
op += ` -O '${options.name}'`;
```

更好的修正：

https://www.npmjs.com/package/sanitize-filename

Start with lib/engines/you-get.js at line 11 and lib/engines/bilili.js at line 15, then trace how options.name is incorporated into the download command. Reproduce the failure with a filename containing a space or | and verify that downloads succeed with such names without breaking command construction.
