It's an emoji... Are there any emojis with only one character? My assumption going in would be that any emoji is > 1 character. Admittedly, despite lots of string processing, I never have to deal with emojis so I guess I'm not sure.

An interesting exercise would be emoji detection during string reversal to preserve the original emoji. I though something like that would be the crux of the article.

Am I wrong about single character emojis?

It depends what you mean by character, there are lots of single codepoint emojis though.
