Inkview: Fix encoding of console output on Windows

To do this we have to "hack" g_print() as the glib people decided Windows consoles should be limited to 255 character code pages forevermore and g_print() converts all strings to the system's ANSI code page without exception.

(see http://stackoverflow.com/q/43927373/2514664 for details)
