When I try to use this function having unicode text, it returns wrong height as its calculating height according the font size but emoticons are coming bigger and taking more height than without unicode.

[text sizeWithFont:[UIFont systemFontOfSize:12.0] constrainedToSize:CGSizeMake(233.0f, 999.0f) lineBreakMode:UILineBreakModeWordWrap];

can real height be calculated having unicodes in the string?
