Displaying Chinese UTF-8 characters in gvim on Windows

By default, gvim on my Windows machines just displays question marks, boxes, or garbled characters when I try to open files with Chinese text. The fix was rather simple:

1. From the gettext project on SourceForge, get libiconv-1.9.1.bin.woe32.zip, which contains bin/iconv.dll. Put that file into gvim's installation directory (for me, it's C:\Program Files (x86)\Vim\vim73).
2. Put this into vimrc:

   set encoding=utf8
   set guifontwide=NSimSun

Note: I'm using gvim 7.3.46 from the official site.

Credit goes to user Tobbe for this answer on superuser.com, which pointed out the key ingredient (iconv.dll).
