+Description: Use utf8 encoding when loading tests
+ Test files are encoded in utf8, normally Python3 uses locale settings
+ and decodes, but this fails when building as locale is not set, and
+ could also be set to some unexpected value.
+ .
+ relational (2.0-1) unstable; urgency=medium
+ .
+   * New upstream release
+   * Now uses Python3
+   * Now uses PyQt5
+   * Bump standards version
+   * Recommends python3-pyqt5.qtwebkit to open the documentation from the UI but
+     it is not a necessity
