xwininfo fails to convert window title string.

[mikolaj]

Hello,

I encountered a problem which makes it impossible to use some programs 
that depend on an ability to retrieve window title:

------------------------------------------------------------------------
mikolaj at xxx ~ $ xwininfo

xwininfo: Please select the window about which you
           would like information by clicking the
           mouse in that window.

xwininfo: Window id: 0x2400068 " (failure in conversion from UTF8_STRING 
to ANSI_X3.4-1968)"

   -geometry 1400x996+0-0
--------------------------------------------------------------------------

The window I targeted was firefox browser with exactly one tab opened,
on website http://allegro.pl. I am not sure if I can include the title
(it is fully visible on the window bar) here as it contains non-english 
characters. However the url is valid and one can easily check if this 
behaviour can be reproduced. Moreover I wasn`t able to find any other 
website that would cause such behaviour.

The relevant applications versions:

xwininfo-1.1.2
libX11-1.4.4
xorg-server-1.11.2-r2

The system is GNU/Linux, stable gentoo.
