Subject: bug#27403: 26.0.50; Indentation misalignment with Unicode code points >65535
Date: Sat, 17 Jun 2017 02:28:41 -0400 [thread overview]
Message-ID: <5bd704e4-b3e4-bcd3-eea6-66856fc47dd6@gmail.com> (raw)
Hello, I believe I've found an indentation issue. 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.
