Android emojis char size

问题

I'm currently developing a keyboard for android , and i found out some emojis take 2 chars and some take 1 char ,

Is there a way to differ between the two if they are in a string ?

回答1:

Ok i managed to solve this issue by using this lib

https://github.com/vdurmont/emoji-java

in there , there is a isEmoji(string)

   String currentTextStr = currentText.toString().substring(currentText.length() - 2);
   Log.e("emojicon",""+EmojiManager.isEmoji(currentTextStr));

Currently seeing the pattern - if emoji doesn't have browser version of it, then that libs isEmoji()function fails to recognize emojis, like Nr. 927, Nr. 938: http://www.unicode.org/emoji/charts/full-emoji-list.html
