Is ‘the’ used before a number as determiner, when ‘all’ is used before them? [duplicate]

Question

I want to write this sentence in a paper:

All the three characters also have their counterparts in ASCII,

where all the three characters refers to the aforementioned three characters out of a bigger set of characters.

Grammarly suggests that the should be removed to form all three characters (shown in the following figure), but I do not understand why. I understand that simply saying the three characters is correct, as the is a referring determiner, three a quantifying determiner, and they can be used together. Then, I want to put all before them to mean the three characters as a whole.

Thanks to @fev, I found another post in which three answers have discussed the differences between all three and all the three. However, I found them contradictory with each other:

1. Colin Fine’s answer states that all the three cars implies the three cars are not the entire class. The answer also states that all three cars does not exclude this possibility.
2. HannahRose, on the other hand, maintains that "all three cars implies that there are only three cars," which does not agree with the first answer. HannahRose also emphasises the fact that "All three cars already implies that you are referring to specific cars."
3. Prof. John Lawler’s answer makes the situation more confusing, because it states that the two phrases are equal in meaning. Although his answer was not voted up, I looked into Prof. John Lawler’s profile and found that he was an English grammarian. I also did some investigation myself. I found in Cambridge English Dictionary an entry for all:

All means ‘every one’, ‘the complete number or amount’ or ‘the whole’.

...

All with no article

When all refers to a whole class of people or things, we don’t use the:

All children love stories. (i.e. every child in the world)

Not: All the children love stories.

Also an entry for determiners,

What do determiners do?

Determiners have two main functions: referring and quantifying.

According to the findings of my investigation, all three characters and all the three characters are all grammatically correct, but they have different meanings. all three implies that the three are a whole set, but all the three implies that the three are out of a bigger set, which is what I wanted to express.

However, it is obvious that this conclusion does not agree with Colin Fine’s and Prof. Lawler’s answers to some extent. Given that Prof. Lawler was an American, it is possible that the grammar for this use case is different in Britain and in American. But I do not know for sure. Anyway, I would like to request a definitive answer on the differences between all the three and all three.

Answer 1

If you use "all the three", it needs to be specific.

The specific rule is just about the only reliable one: "All the three characters I pointed out also have counterparts in ASCII". But many others do not."

This specificity can also be stated like this:

"all of the three characters I pointed out etc."

all of these or those three characters I pointed out

If there is a relative clause like that as in [all the three characters (that) I pointed out], the "the" is justified. It functions the same as: All those/these characters I pointed out

Versus: "All three characters also have counterparts in ASCII". etc. That's the difference. Specificity with a relative clause, for example.

1. "All three characters also have counterparts in ASCII." [general]
2. "All of the [or those, these] three characters also have counterparts in ASCII." [specific, pragmatically, as opposed to other characters that are not ASCII]
3. "All three of the [or those, these] characters also have counterparts in ASCII" [specific, pragmatically, same as 2)]
4. "All the three characters I pointed out have counterparts in ASCII" [but not, for example, the ones I didn't point out or other ones somebody else mentioned]

For me, 2, 3 and 4 are semantically the same. They are specific.

"the" as definite or specific The is used to refer to a specific or particular member of a group. For example, "I just saw the most popular movie of the year." There are many movies, but only one particular movie is the most popular. Therefore, we use the. grammar from Purdue University

Another example: Imagine a game played in the street.

• All boys on the street must be wearing shoes. [a general idea]

• All the boys on the street must be wearing shoes. [those specific boys but not, for example, the boys in gardens along that road]

• All the dogs on the beach must be leashed. [implies dogs elsewhere do not need to be leashed. It refers to those four].

• All dogs on the beach must be leashed. [a general statement].
