Fixed a serious bug in windows/utf16.cpp that went unnoticed for this long: we wanted utf16UTF8Count(), not utf16RuneCount(), in toUTF8(); any non-ASCII text had the wrong number of bytes, and thus random heap corruption. The string "鎿嶄綔鎴愬姛瀹屾垚銆" (taken from the completely unrelated #337) and the Set Button Text button was enough to trigger this.
