Think of the example of SHY (soft hyphen), used to mark possible
hyphenation
points in a word. A while ago we had a discussion on this list where
there was
an interesting minimal pair of German compounds:
Wachs|tu-be (tube of (or made of) wax)
Wach|stu-be (guard room)
The word boundary (which is also an hyphenation point) is marked as |,
a secondary
hyphentaion point is marked with -. In other word, each word has two
SHYs in it,
but not both in the same location.
I can remove the SHYs from these words, and if the text is not broken
across lines
at that point, its semantic for the human reader doesn't change. With
context, the
text is unambiguous, but if there isn't enough context, the text is
clearly ambiguous.
However, equally clearly, by leaving the SHY in the text, it is (in
its internal
representation) entirely unambiguous, even if that semantic difference
is not
surfaced to the reader (except if a line break fortuitously happens to
be present
in the first half of the word).
Of course a (good) screen reader could pick up on the difference and
split the
compound correctly when pronouncing it.
Interesting. But suppose the typesetting rules for German were changed
so that hyphenation is no longer permitted, or so that (as in many
languages) hyphenation points are determined strictly from the letters.
These two words can no longer be distinguished by the position of SHY.
But the good screen reader would still need to distinguish their
pronunciations. Is there any type of character which could be defined,
in Unicode, to preserve this distinction, but to be completely hidden in
display? Perhaps some kind of zero width morpheme break character? I
suppose ZWNJ or WJ could be used, but they might have other undesirable
characteristics. (ZWNJ would inhibit formation of an st ligature in
certain fonts in Wachs|tube, but maybe that is also desirable.)
