I get this error when trying to import data via 'cadastre' module in a PostGIS database :

<pre>
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 104: ordinal not in range(128)

Version de Python : 2.7.5 (default, May 15 2013, 22:44:16) [MSC v.1500 64 bit (AMD64)]
Version de QGIS : 2.18.10 Las Palmas, 59e0f78
</pre>

It look like the use of the str function in the connector create this error.

Have you some solution to fix this ? Is it a configuration problem with my environment ?
I tried both on a Debian and Windows platform and each time with the 2.18 version of QGis I have this error.
