Clique novamente para salvar e depois é só fazer os testes, lembre-se que os comentários do blogger podem demorar uns minutos para aparecer, normalmente não demora, então se não aparecer na hora é normal, mas isso não quer dizer que deu errado, nos testes que fizemos demorou uns 2 minutos para ser visível o comentário com emoticons no blogger.
E o melhor de tudo sobre esses emoticons para colocar no blog é que você pode criar os seus emoticons facilmente, repare que os trechos que se repetem varias vezes:
_str = _str.replace(/:k/gi, "<img src='https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEib8vLimMqmvaVrP6cjyFSkiGYgrcvY4NMdzfg4YtMujnEkhapLErehlrHHEA71xvt_b6uZLx7hxBZ_mVwN713gtxw7_ZBWdAXvGKWyhbMyXtUd0GJAqVvPbBgoPCq5qwCLp1X7T6F_A1g/s800/emoticon-0103-cool.gif' alt='' class='smiley'/>");

&#160;
Cada um numa parte do código é repetido apenas trocando o endereço da imagem e o código para o emotion , portanto se trocar o endereço da imagem: https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEib8vLimMqmvaVrP6cjyFSkiGYgrcvY4NMdzfg4YtMujnEkhapLErehlrHHEA71xvt_b6uZLx7hxBZ_mVwN713gtxw7_ZBWdAXvGKWyhbMyXtUd0GJAqVvPbBgoPCq5qwCLp1X7T6F_A1g/s800/emoticon-0103-cool.gif'

E o código :k irá criar um novo emoticon, apenas tome cuidado para não apagar nem colocar nada a mais no código e não usar o código de imagem repetido ou seja :k só poderá haver um deles, então escolha outros caracteres para ser o atalho para os novos emoticons.
