1. Go to the *scratch* buffer or create a new buffer in fundamental mode
2. Observe that Emacs is quite responsive when typing random ASCII
   characters
3. Insert (C-x 8 RET) a CIRCLED DIGIT EIGHT into the buffer
4. Continue typing: the buffer update is slower than before
5. Switch to another buffer and observe that Emacs is still as
   responsive there as in step 2 once the slow buffer switch
   happened.
Extra info:
1. This issue is
   - NOT in Emacs 24.5 (GNU Emacs 24.5.1 (i686-pc-mingw32) of 2015-04-11
     on LEG570 downloaded from http://gnu.xl-mirror.nl/emacs/windows/
   - already in emacs-25.0.90-i686-w64-mingw32 (dowloaded
     from the same http://alpha.gnu.org/gnu/emacs/windows/)
2. Characters from the ISO-8859-1 set (e.g. LATIN SMALL LETTER E WITH
   ACUTE=C-x 8 ' e) do not have this problem.  Upon consideration, it's
   maybe a question of font: this issue doesn’t happen for “RIGHTWARDS ARROW”
   (C-x 8 a >).  C-u x = reports:
                     position: 125 of 144 (86%), column: 54
                    character: → (displayed as →) (codepoint 8594, #o20622, #x2192)
            preferred charset: unicode (Unicode (ISO10646))
        code point in charset: 0x2192

          general-category: Sm (Symbol, Math)
          decomposition: (8594) ('→')
        There are text properties here:
          fontified            t
3. In all versions I tested for this report, C-u x = reports the same
   information for CIRCLED DIGIT EIGHT (I've replaced the troublesome
   unicode character by `(8)'):
                  character: (8) (displayed as (8)) (codepoint 9319, #o22147, #x2467)
          preferred charset: unicode (Unicode (ISO10646))
