In order to create a full function chat window, I want label can show little pictures for example :
Hi

hello
However TextList in NGUI can only change the color of texts, but cannot add some other elements such as pictures or hyperlinks.
I tried to create a Sprite to show an image, and calculated the position to cover the text which represent image, but the height of a line cannot adjust for image bigger for characters.
I want to know is there any method to realize a chat window which allow users to insert happy faces

like this forum.
And there is another problem, in my font file, there are some large characters which as three times as the rest, but in Label, they do not have enough space, other characters cover the extra places, Can some one help to to deal this problem?
Please forgive my pool English. Thank you.
