I never understood why spaces and tabs cannot be displayed with

Because a tab is not a printing character, it is a *control*
character, and its semantics are poorly defined.
Tab is *not* just n spaces. It is "move the head/platen to tab stop"
and "tab stop" is defined by the end user.
Be that as it may, that still doesn't address ASCII 032 not having the
option of being visible so as to visually be able to differentiate it
from a tab, on screen that is.
I've used editors where tabs and spaces were visible.
It got kind of annoying after awhile.
Although, come to think of it, I didn't try using those editors for
looking at IAS code. Hm.
On the printouts, I would prefer things
be as they are, except maybe being able to tell the printer to use the
computer's definition of the tab. I think someone mentioned that the
printer *always* uses 8.
That was probably me. And it's a default -- some of the old dot-matrix
printers, at least, had the ability to "set tabstops", IIRC.
I *thought* I remembered my printer having that feature in the
documentation (tho I never used it), my Star NX-1000 (IIRC), my first
color printer for my Amiga 500.

I'm not so sure I necessarily want "A font for programming must be
monospaced", but the rest of the description sounds great! I like
monospace in email (especially when doing or viewing ASCII art). I like
monospace on the command line, vim, but probably not in Firefox.
Heh. If it's not printed, I prefer monospaced.
I'll check it out.
But I distinctly remember on my Amiga computer being able to modify
fonts myself. And a quick search for "linux font editor" thru Viv?simo,
the first page of 20 results netted 9 pages of interest.
I made a few fonts with the Amiga Font Editor. It was fun, and you soon
realize that making *good* fonts is not an easy task.
Amiga Fonts could also be in color, which made it possible to do a slick
version of Rogue... not until the tile-based nethacks came out did I
ever see anything similiar on another platform.
Funny you should mention nethack. Just hours ago, when searching
Vivísimo for "linux font editor", among the hits was a linux console
text editor that was ported from DOS (previously from Atari (previously
from something I never heard of and don't remember)) to linux just so
that he could edit the linux console font so that he could change the
"@" to look like a person, the whatever-that-character-was to look like
a dog, and so forth. It was actually quite good. He remarked that the
tiles version didn't allow you to see more than one room at a time
whereas you could see the whole field and everything in it with his
version. I'd give the link, but I closed it hours ago.
But I don't see why any of the other fonts I mentioned should be
untouchable. It would be nice to have all fonts on my system show a dot
or a slash in the zero. It would be nice them all have a very short
horizontal half roof on the left side of a vertical line for the lower
case L (whether it has a base or not, I don't care). It would be nice
for all fonts on my system to have a down sloping half roof on the left
side of a vertical line with a full base for the number one. It would
be nice for them all to have a vertical line with the top half replaced
by a small but visible dot for a lower case I and an upper case I that
looks like the cross section of an I-beam.
You mean you want something like:
xxx xx
xx xxx
xx xx
xx and xx
xx xx
xx xx
xx xxxxxx
?
Yup. And:
xxxxxx
xx xx
xx
xx and xx
xx xx
xx xx
xxxxxx xx
and:
xxxxx xxxxx
xx xx xx xx
xx xxx xx xx
xx x xx OR xx x xx
xxx xx xx xx
xx xx xx xx
xxxxx xxxxx
or something thereabout.
The zero should always be distinctive from the oh, and not just in
girth. Distinction by girth is so stupid. It's easy to know which one
is which when they are next to one another, but when they are not, and
context doesn't help you, good luck!
But just as nice, I would like to have fonts that have a space (ASCII
032) that shows something visible on the screen but is invisible in a
printout. Even if tabs don't show anything visible, at least something
visible for ASCII 032 would visually distinguish it from the tab.
Changing the font on your system would do that, I would think.
Except possibly in printouts that are postscript rendered using my
system fonts, the same ones that have a space that is somehow visible on
the screen.
