Regression introduced by d84741a4bf.
The mentioned commit actually is a good thing, because we now get the
output from the X session.
Unfortunately, for the i3wm test, the i3-config-wizard prints out the
raw keyboard symbols directly coming from xcb, so the output isn't
necessarily proper UTF-8.
As the XML::Writer already expects valid UTF-8 input, we assume that
everything that comes into sanitise() will be UTF-8 from the start. So
we just decode() it using FB_DEFAULT as the check argument so that
every invalid character is replaced by the unicode replacement
character:
https://en.wikipedia.org/wiki/Specials_(Unicode_block)#Replacement_character
We simply re-oncode it again afterwards and return it, so we should
always get out valid UTF-8 in the log XML.
For more information about FB_DEFAULT and FB_CROAK, have a look at:
