Enabling flag "fastscroll" on net-irc/xchat-2.8.8-r1, using x11-libs/gtk+-2.22.1-r1, x11-libs/pango-1.28.3, x11-libs/cairo-1.10.2-r1 and font "Terminus 11" causes «ű»(LATIN_SMALL_LETTER_U_WITH_DOUBLE_ACUTE) to be rendered as a black square. Other characters seem unaffected and this bug doesn't manifest itself when using an anti-aliased font(DejaVu, Droid, etc...)
Which version of media-fonts/terminus-font is that?
4.30 and 4.32 alike trigger this bug
