Regardless of the issue reported here, I would advise against setting
the UTF-8 language environment on MS-Windows. Doing so is likely to
screw you in some situations. For example, that sets up the encoding
of communications with subprocesses to use UTF-8, something that only
works with pure ASCII text and command-line arguments, and breaks
otherwise on Windows.
You shouldn't need to do this, not in Emacs 25 anyway.

Fixed on the emacs-25 branch. The reason was sub-optimal definition
of the default fontset wrt to fonts that cover symbols and punctuation
Unicode blocks.
Thanks.
