In GNU Emacs 24.2.93.1.
char-acronym-table has three entries with "XXX". They are from
lisp/international/characters.el :
> (let ((c1-acronyms '("XXX" "XXX" "BPH" "NBH" "IND" "NEL" "SSA" "ESA"
> "HTS" "HTJ" "VTS" "PLD" "PLU" "R1" "SS2" "SS1"
> "DCS" "PU1" "PU2" "STS" "CCH" "MW" "SPA" "EPA"
> "SOS" "XXX" "SC1" "CSI" "ST" "OSC" "PM" "APC")))
These are the three C1 control characters that are listed with no name
in Unicode and that aren't part of ISO/IEC 6429.
These had the acros PAD, HOP, SGCI in draft DIS 10646, but weren't
standardized (not accepted to ISO 10646).

I don't like the acronym feature showing different characters the same,
so I suggest that "XXX" is replaced by the inofficial PAD, HOP, SGCI
here.
Alternatively, if that is not OK, that the target c1-control for
glyphless-char-display skips these three characters.

If this list is automatically generated from the C1 control code list,
then perhaps that generating function should be removed?
If not, I think your patch is OK, if I understand what it's doing here.
(I may very well be not.)

I'm okay with applying this, thanks.
