Unlikely, this has been really designed this way on purpose.

Weirdo, I don't see this and actually, NET_WM_NAME is set in main.c to
"Xfwm4", so there is no UTF8 involved in there...

Try this:

    xprop - root | grep WIN_SUPPORTING_WM_CHECK

Note the value, then do

    xprop -id <value> | grep NET_WM_NAME

What does it give?
