No I make no confusion: <wbr> is a formatting HTML element, SHY (or
­ in HTML syntax for the defined entity) is a character. Both play
equivalent roles in HTML,
Not at all.
except that ­ has a defined behavior to
insert an hyphen at end of broken lines, where <wbr> would adopt a
language-dependant behavior (not all languages use hyphens at end of
lines to mark words that have been split by breaking lines).
Quite the opposite. The effect of SOFT HYPHEN is expected to be
language-dependent (though it hardly is in web browsers):
http://www.unicode.org/reports/tr14/#SoftHyphen
Normally, it causes hyphenation, with a hyphen inserted when adequate.
This is quite different from a direct break opportunity, which is what
<wbr> means in browser practice, being standardized in HTML5:
http://www.w3.org/TR/html5/text-level-semantics.html#the-wbr-element
There is nothing language-dependent about <wbr>, in theory or in
practice. It is never expected to result in the addition of a hyphen,
and it never does that.
When Netscape invented <wbr> long ago, they chose a cryptic name, which,
when expanded (to “word break”), has seriously misled many people into
thinking that it is for suggesting breaks inside human-language words.
Its primary use is for breaks inside strings that are *not* words.
(Exceptionally, it sometimes has use inside words: you might wish to
write e.g. tax-<wbr>free, but there the point is that a simple string
break is OK, since the “-” is part of the word and no hyphen needs to be
added when the word is divided.)
