bug#23946: 25.0.91; Unicode issue on OS X (Emacs 25)

[Артур Файзрахманов]

Hi!  I'm using Emacs pretest version 25.0.91.1 on OS X El Capital.  If I
launch Emacs from GUI (e.g. from Applications folder or using Spotlight)
Unicode characters in mode-line are rendered wrong (I use diminish mode
to substitute some minor mode names with Unicode characters).  This is
not a case if I start Emacs manually from shell.


In GNU Emacs 25.0.91.1 (x86_64-apple-darwin13.4.0, NS appkit-1265.21 Version 10.9.5 (Build 13F1603))

Which Unicode symbols are you referring to?
In particular, are you talking about multi-color symbols (Emoji) or
other Unicode symbols?

Because, support for multi-color fonts was deliberately disabled in
commit 9344612d3cd164317170b6189ec43175757e4231.

So the SNOWMAN (U+2603) symbol will be displayed in black/white, but not
in color. ☃

This was also mentioned in NEWS:

> ** On the OS X Cocoa ("Nextstep") port, multicolor font (such as color
> emoji) display is disabled.  This feature was accidentally added when
> Emacs 24.4 included the new Core Text based font backend code that was

> again once it is also implemented in Emacs on free operating systems.
> If some symbols, such as emoji, do not display, we suggest to install
> an appropriate font, such as Symbola; then they will be displayed,
> albeit without the color effects.

When you say ‘start Emacs manually from shell’, do you mean run the GUI
Emacs from the shell, or run it within the terminal?

How are you running it, just typing ‘emacs’?

I use `diminish-mode` to squash some minor mode names to single unicode
symbol, here are some of them: ⨠ ¬ ↻ ⧊ ⎌.  The issue appear not only for
Unicode symbols, but also for cyrillic characters too.

Yes, I mean GUI application.  I have two ways to launch GUI app — by
clicking on Emacs icon (the issue appears), and by command invocation in my
terminal; I use `fish` shell with default Mac OS Terminal app, the exact
command I'm using is

fish -c '/Applications/Emacs.app/Contents/MacOS/Emacs&'

Regards!

Can you please check the value of the $LANG environment variable within
emacs when you load it each way:

(getenv "LANG")

This is set from the system when loaded via spotlight, but from the
terminal's environment when loaded at the command line. It might have an
effect if it's different, I'm not sure.

Ok folks, I've installed just installed Emacs-pretest-25.1-rc1-universal
(from emacsformacosx.com), with this version issue does not appear!  Likely
it was already fixed! Thank you!
