At first, I suspect that FLTK2 does not support multi-national language dispaly. So I wrote a small program to test it. I used: "g++ -o fltkhello1 fltkhello1.cxx -I/usr/local/include -L/local/lib -lfltk2 -lXext -lXft -lX11 -lXi -lm" to compile. The result is not not satisfying. With the help from fltk-dev mail list, I tried "fltk2-config --compile fltkhello1.cxx" and got correct result. In fact, "fltk2-config --compile fltkhello1.cxx" will execute the following command to compile: gcc -I/usr/local/include -I/usr/include/freetype2 -Wno-non-virtual-dtor -o fltkhello1 fltkhello1.cxx -L/usr/local/lib /usr/local/lib/libfltk2.a -lX11 -lXi -lXinerama -lXcursor -lXft -lpthread -lm -lXext -lsupc++ The interesting part is: my previous faulty compile command made my program only recognize type1 font (such as Bitstream Charter), and no truetype font is recognized. The problem was corrected by calling "fltk2-config --compile fltkhello1.cxx". Because in my desktop, all the Chinese glyphs are provided by truetype font, it caued FLTK2 program won't dispaly Chinese glyphs.

I also add some code in Dillo 2 source code to hardcode fontname to be used to draw text, I found that only typ1 font was recognized, all truetype fonts are not recognized.

Hmm...I've always used Bitstream Cyberbit for Asian text, and the mighty wikipedia claims it's TTF ( http://en.wikipedia.org/wiki/Unicode_typefaces ) Dillo's configure.in has AC_MSG_CHECKING([FLTK2]) if sh -c "fltk2-config --version" >/dev/null 2>&1 then AC_MSG_RESULT(yes) LIBFLTK_CXXFLAGS=`fltk2-config --cxxflags` LIBFLTK_CFLAGS=`fltk2-config --cflags` LIBFLTK_LIBS=`fltk2-config --use-images --ldflags` else AC_MSG_RESULT(no) AC_ERROR(FLTK2 must be installed!) fi to get the fltk flags...

Maybe the -I/usr/include/freetype2 option is needed on your system to get the right freetype includes? You might try export CPPFLAGS=-I/usr/include/freetype2 before calling the dillo configure script to make sure gcc looks in /usr/include/freetype2 first when searching for freetype includes.
