i realized totay morning that 'unifying' the text based "-" (so called dash) and math based "-" (minus sign) is big mistake in ascii ...this is something a bit like using "O" sign for both 0 and O

i will maybe not even wider explain why its big mistake as i think its somewhat understood (in c for example it removes a dash sign from normal usage when
you really would like it)

the question is is it somewhat possible to mend it some way? by mending it i mean introducing usage of dashes in c (by introducing i mean if i would write
compiler but want base it on ascii can i introduce dashes (like allow them in
identifiers or some syntax constructions) without reaching for unicode?
Is there something maybe in thoise ">127" or "<32" fields which i could use for dash?

You would immediately conflict with UTF-8 as there is no designation
whether is a text file is ASCII or UTF-8. I assume that all text files
are now UTF-8.

Changing ASCII at this point and time is not going to happen.

In fact, there is such a designation, but it is optional.

Look in those 127 characters, and you'll find there are nowhere near
enough characters for the use we make of them.

I'm in the UK, and the currency symbol is £ - pound. Not to be confused
with #, the hash sign, which Americans sometimes call pound...

That £ isn't in the first 127, and we used to have regional variations
of the 7-bit character set replacing things we don't use much with some
we do.

It so happens someone in another group pointed me at a 1950 exam paper
which involved UK money. In those days the currency was the pound,
divide into 20 shillings, each divided into 12 pence.

You could write a pound: £1.
Or a pound and 2s: £1/2. Or 1/2/- is also acceptable.
Or 2 shillings and 6 pence: 2/6d.

Writing arithmetic with the slash we always use for division instead of
÷, was a pain in the ****. But there's no easy way to type ÷ (unicode
F7), so we take a shortcut.

In a way we _have_ changed ASCII. We've extended it, dropped the
regional variations, and called it Unicode.

But assuming they are all UTF-8 is dangerous... especially if you're
looking at old archives.

You can check if a file is UTF8. Whilst mathematically there is a chance
of a false positive, if the file contains more than a few non-ASCII characters,
the chance of accidentally conforming to UTF8 drops to almost zero.

and btw there is this dash sign in utf-8 ? whit is its code how code in bytes?

im writing my extended c (or micromodular c or how to call it, may be called in various naming) compiler (slowly but slowly, im not in hurry) and i feel a lack of few characters and this dash (not to confuse with minus sign) is one of them

maybe indeed i will just take few from unicode and 'add' them as a language important operators
(i dont need many but might add 5-10 or sometging)

fir <profesor.fir@gmail.com> writes:

There are several dashes (for example, a figure dash, an en dash and an
em dash) as well as more than one hyphen. There is also a mathematical
operator symbol for minus.

That's a hyphen. A hyphen connects two words to make a compound, like semi-final.
A dash is a punctuation mark. It indicates a short pause. Generally it is used instead
of parentheses, but if the closing parethesis is at the end of a sentence, there is no
closing dash.
You type a hypen without any spaces between the two hypenated words, and a dash with
two spaces to separate the dash from the text. In both cases, ASCII 45 (0x2D) can be used,
though ideally a dash is slightly longer than a hyphen.

Yup, the Notepad in Windows 7 did not like it. Or a Notepad like

Did you mean <https://en.wikipedia.org/wiki/Byte_order_mark>?

You can, but it causes problems, particularly on Unix-like systems.

For example, if you want to concatenate two UTF-8 files that don't have
BOMs, you can just concatenate the bytes. If the second file has a BOM,
you have to recognize and delete it (unless you want to have a stray
ZERO WIDTH NO-BREAK SPACE in the middle of the new file).

A *lot* of software for Unix-like systems makes assumptions that are
broken by BOMs. Just one example, the "tail" command prints the last N
lines of a text file (default N=10); it's not going to add a BOM to its
output.

For more fun, there are at least two common types of dash - the "en
dash" and the "em dash". The "en dash" is a little longer than a
hyphen, and should be as wide as a lower-case "n" in the font. It is
used for ranges, such as "a-z". An "em dash" is as long as an
upper-case "M" in the font, and is used /without/ spaces somewhat like
parentheses or a colon. (If you don't have an em dash symbol, then you
use a shorter dash with spaces.)

In LaTeX, LibreOffice, and some other software, you can get an en dash
by writing "--", and an em dash by writing "---". If you are in maths
mode in LaTeX, then "--" will give you a figure dash, which is basically
like an en dash but with a width matching the digit "0" rather than the
letter "n".

Of course, the "rules" of typography are subject to change, fashion,
language, personal preference, and so on.

And while careful use of dashes can help a document look a little nicer,
they are extremely hard to distinguish and therefore much more
questionable in programming. Can anyone distinguish reliably between these?

a­‐b
a-b
a−b

The first is a Unicode hyphen, the second a hyphen-minus (ASCII 45), the
third is a Unicode minus sign. Would anyone /really/ want a programming
language that treats the first of these as a single identifier and the
second as a subtraction expression?

If a language wants to allow hyphens inside identifiers, then the only
sensible solution I see is to insist that operators such as "-" always
be surrounded by spaces. It's easy to distinguish "a-b" and "a - b".

i first see but i have only partial knowledge on english language..both dash and hypen dont say me too much when i read or write it...in polish there is word "myślnik" for both of them it seems, and "minus sign" (znak minus) fir third (this mathematical one)

what i was saing is mostly that having one - for both minus sign and dash/hypen makes problems ..you cant use dash and hypen when you would need them (especially probably hypen in identifiers but maybe dash also would be handy)

so, after all it seems i need 3 signs for 3 things? is there unicode for them?
if i would write compiler (or give it for someone to be written) i could in fact add them to language, someone would then need write editors allowing them to be put in code from keayboards easily but all in all this is not a big problem i guess
(not that i like unicode so much, im not sure, but dont want to berakl standards so i could just go with that unicode after all)

of course, i think i would like 3 of them, this longest is very distinguishable from the two abowe (and i like such long minus though it should be a dash) this first hypen is ok i think it should be maybe the shortest , and mathematical minus or negation (i remember i once wad writing something that suggested that maybe minus and negation should be also two separate, though i not fully remember the course of though ) probably should be of middle length and maybe a bit shifter to right
(i man im not sure if minus and negation introduce as a two but if two then the negation should be shifted to right) anyway hypen shortest, minus middle lenght, dash longest

BTW, I started programming in 1975 on a Univac 1108, a six bit
character, six byte word, 36 bit word machine. No lower case characters.

I ported our software to the CDC 7600 in 1978, a six bit character, ten
byte word, 60 bit word machine. Also no lower case characters.

it still not fully clear to me but it seems i should use this asci one as a minus and find some unicode as a hypen only (it seems (though im not sure) that this asci one they name as hypoen-minus becouse its both hypen and minus...in my context it should be probably only minus)

is there maybe some specially designed for denoting negation but not subtraction?,
like -2-1-2-3 would denote -2, -1, -2, -3 not subtractions? (same with + as denoting positive but not addition)

in some contexes its quite usefull as i than could pass arguments to function f(-1 -10) without commas (",") otherwise its passing not -1,-10 but -11

this negation sign is somewhat disputable becouse it introduces burden of typing it where in old form some may use plain minus sign and uses "formatting", also there is a question if c form is not to much open if someone may write
a = 2 - 7
with a lot of spaces..as for now im not sure, but seem negation sign wopuldnt be bad to have

Have you heard of Lisp?

;; - is part of the numeric token, not a unary minus:

[1]> (+ -1 -2)
-3

;; 1-2 is a symbol like abc: we can use it as a variable:

[2]> (let ((1-2 "abc")) (list 1-2))
("abc")

While the characters exist I wouldn't recommend using them. Too much

I agree with Andy.

In a C like language that supports a hyphen character and a minus character,
there has to be a clear way for the HUMAN programmer to distinguish them.

c=half-life

Is that c assigned the value of the variable half minus the value of the variable life?
or
Is that c assigned the value of the variable half-life?

fir, it is your language so your choice. But you are going to need to control the font as well to make this work.
I suggest the benefit (allowing hyphenated variable names) is not worth the cost of new character assignments.

in case of zero and O it showed to eb no problem (to have two of them), imo same is with minus and hypen as to distinguishability of the two ...they are differend things... now the situation is just that there is no hypen in c and i think having this would be handy

there is also a question what else to add to the basic set... i wouldnt wnat to add very many many new chars probably but i would add like 7 or so ...*maybe i even would and more but probably the first added would be of most importance (most commonly used)

some propositions? (which one to add)

probably there could be added:
- hypen
- middle dot, middle cross
- 4 arrows
- degree sign
- maybe some new parentheses like << >>, round one, and brackets , like < > but more vertical..
....
in fact more can be gathered and i should maybe chose by need of them to the given language constructions maybe...in fact all unicode may be added as it maybe already added but he wuestion is what should have meaningfull meaning in form of what construction and this is to see

None of these things exist on your keyboard, so you'll need to reinvent
trigraphs. Or quadgraphs.

Nobody will thank you for that.
