bug#19474: 24.4; icomplete fails to insert character with C-x 8

[Eric Hanchrow]

* I started emacs with emacs -Q -nw

* I turned on icomplete by typing ESC x i c o m p l e t e RET

* I attempted to insert my favorite character, "PILE OF POO", by typing C-x 8 RET p i l e RET 

* I saw an error in the echo area: read-char-by-name: Invalid character

* I did not see my beloved character in the current buffer
