Is the article about HN stripping emojis (and some other Unicode code points) from the title of another HN submission?

Yes, it is.

Amazing! So if I ever were to write a blog post e.g. "Why ' ' != ' '", I guess I better title it "Why '\u2744\ufe0f' != '\x20'" to avoid confusion on HN.

Edit: as demonstrated by this very comment.
