I have dump the raw data of my file, I have input 8 'a', the dump data has the line of below: 00000f0 202c 3031 2c30 2220 6161 6161 6161 6161 So I think the encoding should be right. Thanks for your help. I think I still need to use fltk-2.0. I still has one question, why the initialize speed of fltk-1.3 is faster than fltk-2.0. The same example test program, fltk-1.3 take about 0.7 second to display, but fltk-2.0 need about 1.2 second. Someone in the Forum told me it is because fltk-2.0 need to load lots fonts. But fltk-1.3 do not need load fonts? _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
