emoticons

Like the title says. I want to find out if a given java String contains an emoticon. I can't use Character.UnicodeBlock.of(char) == Character.UnicodeBlock.EMOTICONS since that requires API level 19. I found this code for iOS but it isn't really applicable since it looks like java and objective-c handle surrogate pairs in different manners.

I have a txt file of an conversation exported from WhatsApp. WhatsApp supports emoticons in their conversation, and the exported conversation also, to my surprise, contains these emoticons! That is, if I open the text file in a text editor (Text Wrangler on Mac 10.8) I can see the emoticons. The text file is encoded in UTF-8 and there are no resources associated with the file that I can tell. Can anyone explain to me how these emoticons are being included in the text file and how they are accurately being interpreted by the Text Editor? Is this related to the character encoding at all? Are

I am getting the text size of a string with this textSize = [[tempDict valueForKeyPath:@"caption.text"] sizeWithFont:[UIFont systemFontOfSize:12] constrainedToSize:CGSizeMake(280, CGFLOAT_MAX) lineBreakMode: NSLineBreakByWordWrapping]; The only problem I have is that if the string only contains an emoji, my app crashes. Is there an easy way to check for emojis or do I have to create an array with all possible emojis and then check for them using that? error: -[NSNull sizeWithFont:constrainedToSize:lineBreakMode:]: unrecognized selector sent to instance 0x3aa88a60 if ([tempDict valueForKeyPath:

I'm trying to make a plot with emojis in ggplot2. What I want is to show emojis instead of labels or show like geom. This question in Stack is very similar to my problem, but it does not solve it either, the answer is quite manual and I need to make automatic (my real data frame has 3000 rows). Just to clarify in this plot below I want to show emojis instead of text labels or within the bars. But seems impossible. After trying differents solutions I'm stacked so any help would be appreciated. I read different ways to face the problem like here , here , here . My last try was like this: mult

I am working on a chatting application in WPF and I want to use emoticons in it. I am working on WPF app. I want to read emoticons which are coming from Android/iOS devices and show respective images. On WPF, I am getting a black Emoticon looking like . I somehow got a library of emoji icons which are saved with respective hex/escaped unicode values. So, I want to convert these symbols of emoticons into UTF-32/escaped unicode so that I can directly replace related emoji icons with them. I had tried to convert an emoticon to its unicode but end up getting a different string with couple of
