地上霜，举头望明月，低头思故乡。long word wrap is
also supported: abcdefghijklmnopqrstuvwxyz12345678
90abcdefghijklmnopqrstuvwxyz12345678901234567890

the difference between autoWrap.wrap(text,200,"14px Arial") and autoWrap.wrap(text,50) is that if you provide the font autowrap will use the font to calucate the width of text. if not autowrap will only calucate the word for 1 length for en char and 2 length for chinese char and other unicode char which char code is bigger than 255.
