While the article title is true (errant is a very specific and concise word), to me it did not convey clear enough that this is just ucs-detect / unicode support (compliance?) ranking. The article title "State of Terminal Emulators in 2025" implied a larger comparison of terminal emulators than just ucs-detect.

Personally I also question the practicality or usefulness of this table because why should I care about having "the best unicode support"?

Curious, I briefly compared top ranked emulator (ghostty) on how fast it can print 10000 lines and it took 432ms compared to alacritty, ranked 18 (50ms), and Terminal.app, ranked 29 (50ms). If this is the trade-off to have the best unicode support, why should I want it? Why does it matter?

How fast my terminal can print 10000 lines is pretty far down the list of requirements I have, who cares as long as it is fast enough? To me it is as irrelevant as who has the best unicode support.
