" " " " and "\u00A0" have
nothing, NOTHING to do with UTF-8.
There is a character -- an abstract unit in a "script" (a writing
system;
we are using Latin right now) -- called NO-BREAK SPACE by the Unicode
Standard and ISO/IEC 10646. Unicode and ISO/IEC 10646 assign this
character an integer number, 160, which is A0 in hex.
UTF-8 is an encoding scheme that provides a way of representing any
of the approximately 1.1 million possible abstract characters in Unicode
as a sequence of 1 to 4 bytes.
