You need at least FLTK 1.3.0 to render UTF-8. Also, as Nikita said, some
compilers do not like UTF-8, so make sure that yours does . Last but not least,
right-to-left scripts do not always render correctly on all platforms. There is
not much FLTK can do about it, but we have added a function that may help you:
void rtl_draw(const char* str, int n, int x, int y)
That would look something like this:
#include <FL/Fl_Box.h>
#include <FL/draw.h>
class RTLBox : public Fl_Box
{
public:
RTLBox(int x, int y, int w, int h, const char *l=0)
: Fl_Box(x, y, w, h, l) { }
void draw() {
draw_box();
rtl_draw(label(), strlen(label()), x(), y()+h()/2);
}
};
...and then the rest of your code, using RTLBox instead of Fl_Box.
Let me know if that worked. Also, a screenshot would be very helpful.
