Consider change file name or escape special char?

Under zsh, the filename with "+" char will cause error.

```bash
$ unzip ./OpenVanilla+liu.zip
unzip:  cannot find or open ./OpenVanilla+liu.zip, ./OpenVanilla+liu.zip.zip or ./OpenVanilla+liu.zip.ZIP.
```

Do you consider change the zip file name?

Or, consider using

```
$ unzip ./OpenVanilla%2Bliu.zip
```
