any one know how display Chinese Characters (tradition or simplified) in GD.....? is that something deal with multibyte functions...? i have installed the bundled GD and Libjpeg they all worked perfectly with english words but when i generate a Chinese character, it just display two symbols i've already set the encoding (of php) to BIG5 and even i use mb_detect_encoding() it can show "BIG-5" but when i use ImageTTFtext(blah blah blah , mb_convert_encoding("[Chinese word here]","BIG-5") it pops out 2 symbol the ttf font i loaded is the one distributed by Microsoft (HKSCS) any php experts know how to solve this problem? Thank you all :) Regards, Eddy @ Hong Kong eddy@ifmx.net
