The sample code splits an input string into an array of characters.
They did a really poor job of explaining this (or even showing the
output), admittedly.
The word "word" in the Subject has no meaning here. The code operates
on an input string variable, which may contain any set of characters
(other than NUL, which no bash variable can ever hold). The output
array has one character per element. For example,
'input' -> ( i n p u t )
'foo bar' -> ( f o o ' ' b a r )
