The U+1F176 (" 🅶") should be NEGATIVE SQUARED LATIN CAPITAL LETTER G.But it's displayed as an square with hexel value in emacs GUI (in bothX11 and Win32).
You can browse follow URL to observe the char:https://github.com/syl20bnr/spacemacs/blob/9bafd3f56193edd0ef7babee2f3bf73a50c8e6ae/layers/%2Btags/gtags/packages.el#L102
Could anyone add support for these unicode char range please? Thanks

It displays fine for me in Emacs.  Check the fonts you're using.

Yes, it probably means that a font that can display the character isn't
installed.  It works fine for me, too, and my Emacs is using:

    ftcrhb:-Free-Symbola-normal-normal-semicondensed-*-29-*-*-*-*-0-iso10646-1 (#x1EB5)

So this doesn't seem to be a bug, and I'm closing this bug report.

C-u C-x = shows me that I'm also using Symbola to display this 
character.

Sun Lin, the following is how I have that configured.  Perhaps this will 
be
useful to you:

;; This magic means we fall back to Symbola for all missing unicode 
glyphs.
;; For Debian: apt-get install ttf-ancient-fonts
(set-fontset-font "fontset-default" nil (font-spec :size 20 :name 
"Symbola:"))

That shouldn't be necessary -- Emacs should find the font by itself
automatically (and it does for me without saying anything about
set-fontset-font).

Hi,

Yes, you're right, I switch the font then the char displayed with " not sans symbols" on linux and displayed with "Segoe UI Symbol" on windows.

Change the fontset-default is required, or emacs didn't find correct font to display this char,
Here is "emacs -Q" and "descript-char" show "no font available".

Dose this mean Emacs should find the font but it didn't?

Output of "descript-char" show "no font available" and display an square (emacs -Q with system default font).
             position: 3 of 4 (50%), column: 2
            character: 🅶 (displayed as 🅶) (codepoint 127350, #o370566, #x1f176)
              charset: unicode (Unicode (ISO10646))
              code point in charset: 0x1F176
               script: symbol
               syntax: w 	which means: word
             category: .:Base, L:Left-to-right (strong)
             to input: type "C-x 8 RET 1f176" or "C-x 8 RET NEGATIVE SQUARED LATIN CAPITAL LETTER G"
          buffer code: #xF0 #x9F #x85 #xB6
            file code: #xF0 #x9F #x85 #xB6 (encoded by coding system utf-8-unix)
              display: no font available

Character code properties: customize what to show
  name: NEGATIVE SQUARED LATIN CAPITAL LETTER G

  decomposition: (127350) ('🅶')

Hi All,

Emacs can't display the char 0x1F176 even the font "note sans symbols" be installed, I have to change default font to "note sans symbols" to display the char.
But after following Phil 's mail, I install the font "Symbola", without change default settings (emacs -Q), Emacs can display this char correctly.

B.R.
Lin Sun
