I use describe-char-unicode-data to speak unicode chars in
emacspeak when navigating by character.
That function claims to be semi-obsolete -- and recommends
get-char-code-property instead; however the answers are not
consistent in the two solutions.
Try non-breaking space \240 (octal)
(setq char ? )
160 (#o240, #xa0, ? )
(describe-char-unicode-data char) returns
(("Name" "NO-BREAK SPACE") ("Category" "Separator, Space")
("Combining class" "Zs") ("Bidi category" "Zs") ("Decomposition"
"noBreak ") ("Decimal digit value" nil) ("Digit value" nil)
("Numeric value" nil) ("Mirrored" nil) ("Old name" "NON-BREAKING
SPACE") ("ISO 10646 comment" nil) ("Uppercase" nil) ...)
whereas
(get-char-code-property char 'name) returns
"COMMA NO-SHE IOTA ARABIC DIAERESIS"
also looking up char in ucs-names yields something different
(car (rassoc char (ucs-names))) returns
"NON-NEITHER UNDER CM COMMA"
Note that all of the above is with the unicdoedata file present
and correctly found by emacs.
Also, and perhaps related:
C-x 8 spc inserts non-breaking space correctly; however when you
use C-x 8 ret, non-breaking space doesn't show up in the
available completions -- either using it's "name" or "old-name"

I cannot reproduce any of these. For me, both
describe-char-unicode-data and get-char-code-property returns the same
name, "NO-BREAK SPACE", and from ucs-names I get "NON-BREAKING SPACE",
which is the "Old Name" property of that character.

This also works as expected on my system.
Please dig deeper into your configuration and customizations, the
answer is somewhere there.

Interesting. Any tips on where in my customization/configuration
I should dig:-)

Following-up to myself and Eli:
I moved out my .emacs.d/elpa directory and the problem goes away
--- it's going to be a lot harder to identify the offending elpa
installed package:-)
