With ggtree (Yu et al. 2017), it is very easy to create phylomoji. Emoji is internally supported by ggtree.
Use emoji in taxa labels
library(ggtree)
tree_text <- "(((((cow, (whale, dolphin)), (pig2, boar)), camel), fish), seedling);"
x <- read.tree(text=tree_text)
ggtree(x, linetype="dashed", color='firebrick') +
xlim(NA, 7) + ylim(NA, 8.5) +
geom_tiplab(aes(color=label), parse='emoji', size=14, vjust=0.25) +
labs(title="phylomoji", caption="powered by ggtree + emojifont")
