It’s not a defined emoji. In fact it’s not a defined code point. Private Use Area means that it is specified as having undefined semantics and you can use it for whatever you like. You just happen to have a font that puts a train glyph there. For me, I see a box containing the characters “E01F”, corresponding to the scalar value U+E01F.

It would probably make sense for HN to strip out PUA stuff, given its decision to strip emoji.
- isoprophlex 5y agoAh thanks! Now I get the Private Use unicode stuff. So the question should rather be addressed at my ios device, "why the hell does ios render a train glyph for U+E01F?"

- Freak_NL 5y agoSame reason it renders U+F8FF as something (I've seen it render as the Klingon logo, as Tux; currently some font on my system is using it for a stylized 't' surrounded by brackets), because someone wanted some glyph available not in Unicode. You'll have to ask Apple about the why. Just bear in mind that those glyphs have no meaning at all without the font that includes them. Without the font, you get a □ or better, a block of Unicode tofu — a square filled with the numbers and letters of the hex code for that codepoint.
