[PATCH] Extended Char Intro: Use getwc in example (Bug 25626)

[Carlos O'Donell]

Tested by building the pdf with make pdf and reading the
section to ensure it makes sense.

OK for master?

8< --- 8< --- 8<
In the "Extended Char Intro" the example incorrectly uses a function
called wgetc which doesn't exist.  The example is corrected to use
getwc, which is correct for the use in this case.
