In the three-or-four dot method, it makes a distinction between three dots
(which "indicate an omission within a quoted sentence") and four dots
(which "mark the omission of one or more sentences"), in clause 11.57.
It adds that in the latter, "the first dot it a true period - that is,
there is no space between it and the preceding word".
In the "rigorous method", described in 11.62 through 11.65, the first dot
among four dots is preceded by a space and the last dot "serves as the
true period", if the last part of a quoted sentence is omitted.
This, however, apparently deals with spacing _around_ the four dots
combination. What seems evident to me is that in both methods, when four
dots are used, they should be equally spaced from each other and identical
to each other. Admittedly this is not mentioned explicitly, but it is
implicit in the idea of "four dots" - as opposite to referring to
(three-dot) ellipsis and a full stop.
Thus, I would conclude that if the three-dot ellipsis is regarded as a
punctuation character that is justified on its own, not just included for
compatibility with other character codes, then so would be the four-dot
ellipsis. What we personally think about a particular usage should be
immaterial; it should suffice that the usage exists.
The question is how a four-dot ellipsis could be represented in Unicode in
plain text. Using a horizontal ellipsis and a full stop, in either order,
would not be satisfactory (even in practice, since both the spacing and
the appearance of the dots could be quite unsuitable), so it would be
better to use just four full stop characters, "....". I don't find it
consistent at all to have a separate character for three-dot ellipsis but
not for a four-dot ellipsis, _except_ if the three-dot ellipsis is
regarded as included _only_ for compatibility with other character codes.
The Unicode standard says (in 2.3):
"Compatibility characters are those that would not have been encoded
except for compatibility and round-trip convertibility with other
We can take this position strictly and therefore regard HORIZONTAL
ELLIPSIS as included for such reasons only. But that would be somewhat
inconvenient position, since there is seldom any good way way to create
spaced ellipsis dots except by using the HORIZONTAL ELLIPSIS character.
