(plural soft hyphens)
- the symbol represented by code U+00AD. It is defined by Unicode as a generally invisible character that allows manual specification of a place where a hyphenated break is allowed without forcing a line break in an inconvenient place if the text was later reflowed.
The interpretation of this character varies among standards and some text systems. Unicode defines it incompatibly with ISO 8859-1 which defines it as "[a] graphic character that is imaged by a graphic symbol identical with, or similar to, that representing hyphen, for use when a line break has been established within a word."
