+  Make sure all emoji are formatted correctly and there are no empty lines (no line at the end of file).
+  
+  Test emoji search by searching for the first and last emoji. If broken, a single emoji could be formatted wrong, or an emoji is not supported by Twitter (such as the 'eye in speech bubble' which causes two images to display and messes up the offsets).
+  
+  If there is an error in 'td:plugin:official/emoji-keyboard' when typing into the search bar, add a breakpoint to the erroring line and check if 'me.emojiNames.length' equals 'emoji.length'.
