In an emacs -Q session, when you eval the below, 

(message "'Hey'")

you get

’Hey’

"’Hey’"

Note the difference here:

This is what I get when I do "C-u C-x =" on the first single quote in the message form:

             position: 206 of 208 (99%), column: 14

            character: ' (displayed as ') (codepoint 39, #o47, #x27)

    preferred charset: ascii (ASCII (ISO646 IRV))

code point in charset: 0x27

               script: latin

               syntax: ' which means: prefix

             category: .:Base, a:ASCII, l:Latin, r:Roman

             to input: type "C-x 8 RET 27" or "C-x 8 RET APOSTROPHE"

          buffer code: #x27

            file code: #x27 (encoded by coding system utf-8-unix)

              display: by this font (glyph code)

    xft:-unknown-DejaVu Sans Mono-normal-normal-normal-*-13-*-*-*-m-0-iso10646-1 (#x0A)

Character code properties: customize what to show

  name: APOSTROPHE

  old-name: APOSTROPHE-QUOTE

  general-category: Po (Punctuation, Other)

  decomposition: (39) (''')

There are text properties here:

  face                 font-lock-string-face

  fontified            nil

This is what I get when I do "C-u C-x =" on the first single quote in the *Messages* buffer (C-h e):

             position: 67 of 338 (20%), column: 0

            character: ’ (displayed as ’) (codepoint 8217, #o20031, #x2019)

    preferred charset: unicode (Unicode (ISO10646))

code point in charset: 0x2019

               script: symbol

               syntax: . which means: punctuation

             category: .:Base, c:Chinese, h:Korean, j:Japanese

             to input: type "C-x 8 RET 2019" or "C-x 8 RET RIGHT SINGLE QUOTATION MARK"

          buffer code: #xE2 #x80 #x99

            file code: #xE2 #x80 #x99 (encoded by coding system utf-8-unix)

              display: by this font (glyph code)

    xft:-unknown-DejaVu Sans Mono-normal-normal-normal-*-13-*-*-*-m-0-iso10646-1 (#x6C1)

Character code properties: customize what to show

  name: RIGHT SINGLE QUOTATION MARK

  old-name: SINGLE COMMA QUOTATION MARK

  general-category: Pf (Punctuation, Final quote)

  decomposition: (8217) ('’')

I believe emacs should not be converting all APOSTROPHE characters to RIGHT SINGLE QUOTATION MARK characters. The displayed messages look just plain weird. To fix that, I would then need to replace all 'MSG' (apostrophe MSG apostrophe) type message displays to `MSG' (back quote MSG apostrophe), which is not practical.

Or, is there a defcustom I need to set to prevent this character translation to curvy quotes?

​Question:

Why is emacs converting all single

Thanks for the reply. 

Among all the noise about curved quotes, I missed out the discussion about text-quoting-style. I started paying attention to that only recently when Paul reverted curved quote stuff in the documentation.

I should have looked at NEWS; sorry about that.

I got my answer; I need to set text-quoting-style to 'straight.

For reference,

(progn

  (message "text-quoting-style = default")

  (let ((text-quoting-style))

    (message "'Hey'")

    (message "`Hey'"))

  (message "text-quoting-style = curve")

  (let ((text-quoting-style 'curve))

    (message "'Hey'")

    (message "`Hey'"))

  (message "text-quoting-style = straight")

  (let ((text-quoting-style 'straight))

    (message "'Hey'")

    (message "`Hey'"))

  (message "text-quoting-style = grave")

  (let ((text-quoting-style 'grave))

    (message "'Hey'")

    (message "`Hey'")))

gives

text-quoting-style = default

’Hey’

‘Hey’

text-quoting-style = curve

’Hey’

‘Hey’

text-quoting-style = straight

'Hey' [2 times]

text-quoting-style = grave

'Hey'

`Hey'

I'm not sure what else there could be left to say.
