Hello:
  everyone!
  I am very pleased to see FLTK1.3.0 support for Unicode encoding.
But I found a problem when I initialized unicode fonts. I am by looking at the code and found that the problem lies in the function call XLoadQueryFont.it take a long time when  calling XLoadQueryFont(utf8Wrap.c) function.

Here is my code:when I use zysong18030,it is very slow.when I use iso8859,it is fast.
envirenment:
tinyx: X11R6 4.2
fltk: fltk1.3.0
compiler:powerpc-603e-linux-gcc
cpu: Media 5200


#include<FL/Fl.H>
#include<FL/Fl_Window.H>
#include<FL/Box.H>
static Fl_Font extra_font;

int main(int argc,char**argv)
{
  const char *utfstr="\xe4\xbd\x95\xe3\x82\x82\xe8\xa1\x8c\xe3\x82\x8b\xe3\x80\x82";

  Fl::set_font(extra_font,"-*-zysong18030-*-*-*-*-*-*-*-*-*-*-iso10646-1");
// Fl::set_font(extra_font,"-*-courier-*-*-*-*-*-*-*-*-*-*-iso8859-1");


  window = new Fl_Window(800,600);
  box = new Fl_Box(20,40,300,50,"Hello,World");
  box->box(FL_UP_BOX);
  box->labelfont(extra_font);
  box->labelsize(16);
  box->label(utfstr);

  box1 = new Fl_Box(20,100,300,50,"Hello,World");
  box1->box(FL_UP_BOX);
  box1->labelfont(extra_font);
  box1->labelsize(24);
  box1->label(utfstr);



  box2 = new Fl_Box(20,100,300,50,"Hello,World");
  box2->box(FL_UP_BOX);
  box2->labelfont(extra_font);
  box2->labelsize(32);
  box2->label(utfstr);

  window->end();
  window->show();
  return Fl::run();
}

 I have checked a few days.I have no idea  how to solve the problem, do you have any suggestions?
thanks.
