Subject: 25.1 on Windows (native and cygwin+w32): high CPU load with "wavy"
 characters
Date: Fri, 07 Oct 2016 12:59:14 +0800

When moving in lines with characters such as WAVY LOW LINE or WAVY LINE:

  - Emacs freezes for a while (noticeable) for a fraction of a second or
    even longer,

  - The CPU load of Emacs increases as well (up to 25% on my Windows 7
    machine) in the meantime.

This happens to the "native" as well as the Cygwin-compiled (--with-w32)
versions, but not with the gtk3 version (--with-x-toolkit=gtk3).
