bug#18374: 24.3; term.el error when cd a directory with Chinese name

[Rangi Lin <rangiltw@gmail.com>]

Steps to reproduce :

1. create a directory with Chinese name
         mkdir /tmp/測試

2. start emacs with `emacs -Q'

3. `M-x term'

4. inside term mode
         cd /tmp/測試

Result :

Debugger entered--Lisp error: (error "No such directory found via CDPATH 
environment variable")
   signal(error ("No such directory found via CDPATH environment variable"))
   error("No such directory found via CDPATH environment variable")
   cd("/tmp/\346\270\254\350\251\246")
   #[(string) "\b\306\232\203\b


It only happen if the directory is exist, for example :

     $ cd /tmp/測
     bash: cd: /tmp/測: No such file or directory

but not cd /tmp/測試
