That page seems totally, bizarrely wrong. Am I just reading it wrong?

Looks wrong to me too.
The text font is wrong and even some of the mousetext characters are wrong.

Well, seeing as almost all the characters are just in the HTML source as
regular text and they don't seem to be attempting to set the font to one
of the Apple II true type fonts that are available, it isn't too
surprising that it looks wrong. The mouse text characters at least are
PNG images so should be fairly accurate.

I don't just mean the glyphs. Look at the character encoding ("code point") values. For example, the //c version seems to have inverse in the high-ASCII range and normal in the low-ASCII range.

The Apple IIgs mouse text characters 70 and 71 are incorrect.

FWIW, I put a bunch of commentary in the "talk" page:

https://en.wikipedia.org/wiki/Talk:Apple_II_character_set

Not sure I'm up for straightening it all out.

Feel free to use the images I created here:

Let me know if you need the inverse and flashing glyphs (.gif)

Also, title bar chars replace running man on IIGS. GS also has chars for 8x international languages.

I believe they're the ISO646 character sets (which is how I implemented
them the one time I did).

Applesoft BASIC program to display all 256 TEXT characters...

https://www.applefritter.com/comment/85264#comment-85264

The following version works for both 80 and 40 columns...

NEW
0 TEXT : H$ = "0123456789ABCDEF": W = (PEEK(33) = 80) + 1 : IF W=2 THEN
W$="."
1 HOME : VTAB 3: HTAB 13 * W + 1 - W
2 FOR H = 1 TO 16: PRINT W$MID$(H$,H,1);:NEXT:PRINT
3 FOR V = 1 TO 16: PRINT
4 HTAB 11 * W:A = PEEK (41) * 256
5 LET A = A + PEEK (40)
6 PRINT MID$ (H$,V,1)W$;
7 FOR H = 1 TO 16
8 POKE A + H + 11,C:C = C + 1
9 NEXT H,V

REM 80 COLUMNS
PR#3
RUN
POKE 49167,0 : REM Show ALTCHRSET
POKE 49166,0 : REM Don't show ALTCHRSET

REM 40 COLUMNS
PR#0
RUN
POKE 49167,0 : REM Show ALTCHRSET
POKE 49166,0 : REM Don't show ALTCHRSET

I'm rather fond of this little bugger i whipped up several years ago.

1 TEXT : HOME : PRINT CHR$(17): FOR H = 0 TO 15: COLOR= H: VLIN 0,31
AT H: NEXT : FOR V = 0 TO 15: COLOR= V: HLIN 0,15 AT V * 2 + 1: NEXT
9 TEXT : VTAB 18: IF PEEK (64435) = 6 THEN GET Z$: IF Z$ > CHR$ (31)
THEN POKE 49167 - ( PEEK (49182) > 127),.: GOTO 9

Type any non-control character to toggle alternate character set.
Type any control character to exit.
Remove the PRINT CHR$(17) for it not to force 40 columns.

Thanks, that is clever, short and fast! :)

Similar to IIgs w/mousetext images (Merci pour le lien Antoine), I am
looking to making screenshots of various models of Apple II with this 16x16
pattern of characters.

Not that the TEXT mode characters would have mattered much because the
system software used the graphics mode of the IIGS...

I think the ʺ glyph (I made this up to look like a longer double quote)
should have been ° (degree or masculine ordinal?) in Spanish and Italian.

Swedish was missing a few characters (CP01106.) How many Swedish IIGS's
were sold?

Are these ROM characters set in the IIGS ROM, or in a separate character set
ROM?

I think the character sets are internal to the Mega II.

Your 3 has a zit on its bottom, and I think the blank line should be at the
top of all, not the bottom of all.

These images show the contents of a character ROM file that claims to be from the IIe. The second one is inverted to show where the blank lines are.

It was on one of Antoine's disks.

I prefer this One Liner:

1 TEXT:HOME:FOR I=0 TO 31:FOR Y=0 TO 7:POKE 1024 + 128*Y + I, I + 32*Y:NEXT:NEXT:VTAB 22:PRINT

Here is a small patch (lines 1 & 2) that will print the hex header correctly in both 40 and 80 column mode:

1 HOME : VTAB 3: HTAB 13 * W + 1 - W:L$=H$:IF PEEK(49176) > 127 THEN L$ = " 0 1 2 3 4 5 6 7 8 9 A B C D E F"
2 PRINT L$

That is:

NEW
0 TEXT : H$ = "0123456789ABCDEF": W = (PEEK(33) = 80) + 1 : IF W=2 THEN
W$="."

1 HOME : VTAB 3: HTAB 13 * W + 1 - W:L$=H$:IF PEEK(49176) > 127 THEN L$ = " 0 1 2 3 4 5 6 7 8 9 A B C D E F"
2 PRINT L$

3 FOR V = 1 TO 16: PRINT
4 HTAB 11 * W:A = PEEK (41) * 256
5 LET A = A + PEEK (40)
6 PRINT MID$ (H$,V,1)W$;
7 FOR H = 1 TO 16
8 POKE A + H + 11,C:C = C + 1
9 NEXT H,V

Actually, that soft-switch should be $C01F to detect 80-cols:

1 HOME : VTAB 3: HTAB 13 * W + 1 - W:L$=H$:IF PEEK(49183) > 127 THEN L$ = " 0 1 2 3 4 5 6 7 8 9 A B C D E F"

Thanks for the correction Mike.

The '3' had been on my TO VERIFY list for a while now if Sather was correct or not. Looks like he wasn't. Thanks for the nudge to get this this done.

I also fixed the glyphs being shifted up. Verified on my real Apple ][+.

I've updated the PRINT.ALL.CHARS to work with Applesoft and Integer Basic

AppleSoft

1 TEXT:HOME:FOR I=0 TO 31:FOR Y=0 TO 7:POKE 1024 + 128*Y + I, I + 32*Y:NEXT:NEXT:VTAB 22:PRINT

Integer Basic
1 TEXT:CALL-936:FOR I=0 TO 31:FOR Y=0 TO 7:POKE 1024 + 128*Y + I, I + 32*Y:NEXT Y:NEXT I:VTAB 22:PRINT:END
