Regression introduced by d84741a4bfb6ed2531ec7154479c147d2c9a737c. 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: http://search.cpan.org/~dankogai/Encode-2.84/Encode.pm#Handling_Malformed_Data Signed-off-by: aszlig <aszlig@redmoonstudios.org>
