greenlet.py, worker.py - UnicodeDecodeError: 'ascii' codec can't decode byte 0xe1 in position 13: ordinal not in range(128)

### Step 1: Please describe your environment

* ZeroNet version: 3853
* Operating system: W10
* Web browser: FF
* Tor status: available

### Step 2: Describe the problem:

The merger site is not loading content from hubs, so i taken a look into debug.log and found some errors that MAY be related:

```

```

There is also other error that is for that particular content i want to open:
`... manifest.json fileGet error: [Errno 22] invalid mode ('rb') or filename: u' ...`

Rebuilding database of the merger site & zeronet restart does not help. And on the hub (that seem to me having issue), it do not show anything in the site's zero menu - corner button)

How this can be fixed and where?

Commencez par core/src/Worker/Worker.py à la ligne 108 et comparez le traceback avec le chemin environnant de gestion des erreurs du downloader ; site-packages/gevent/greenlet.py est l’endroit où l’exception se produit. Reproduisez l’échec en utilisant un chemin interne non-ASCII tel que celui affiché dans le journal, puis vérifiez que le contenu du merger se charge sans le UnicodeDecodeError non géré ni une erreur de nom de fichier associée.
