+-   I get a runtime error with `Click` complaining about the encoding
+
+    .. code-block:: python
+
+        RuntimeError('Click will abort further execution because Python 3 was configured to use ASCII as encoding for ...sk_SK.UTF-8, sl_SI.UTF-8, sr_YU.UTF-8, sv_SE.UTF-8, tr_TR.UTF-8, uk_UA.UTF-8, zh_CN.UTF-8, zh_HK.UTF-8, zh_TW.UTF-8')
+
+    This can be solved by :
+
+    .. code-block:: bash
+
+        export LC_ALL=en_US.utf-8
+        export LANG=en_US.utf-8
