To reproduce, start emacs, create a buffer in js-mode, paste in this code, and press C-x h TAB to indent the buffer: let x = /* 👍 */ { foo: 0 bar: 0 } let x = /* ☺ */ { foo: 0 bar: 0 } Both 25.2 and 26.0.50 add one extra space before "bar" in the first first snippet with U+1F44D THUMBS UP SIGN in the comment, whereas the second snippet with U+263A WHITE SMILING FACE properly aligns "bar" with "foo". This appears to happen whenever the character in the comment needs a surrogate pair. This issue also happens in python-mode: "👍", {"a": 2, "b": 3} "☺", {"a":2, "b":3} Interestingly, pressing TAB with one's point on the second line of each snippet to dedent the line yields a correct result for both symbols: "👍", {"a": 2, "b": 3} "☺", {"a":2, "b":3} Just in case those Emoji don't make it through the mail properly, the first snippet in each example contains U+1F44D THUMBS UP SIGN before the map, and the second snippet contains U+263A WHITE SMILING FACE. -Adam In GNU Emacs 26.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.22.15) of 2017-06-17 built on AdamsPC Repository revision: 49c0ff29c2e0243ba35ec17e3e3af49369be43db Windowing system distributor 'The X.Org Foundation', version 11.0.11903000 System Description: Arch Linux Recent messages: Auto-saving... 20 (#o24, #x14, ?\C-t) 21 (#o25, #x15, ?\C-u) 20 (#o24, #x14, ?\C-t) [2 times] Undo!
