This distinction helps re-use of already formatted text, when line breaks and soft hyphens inserted during word wrapping have to be removed to convert the text back into its unformatted form. The purpose of the soft hyphen here is to distinguish it from any regular hyphen that might have been part of the original spelling of the word. Here, SHY is a visible hyphen that is usually visually indistinguishable from a regular hyphen, but has been inserted solely for the purpose of line breaking.

This is the application context originally considered by the EBCDIC and ISO 8859-1 standards and implemented in many VT100 terminal emulators. The SHY character is also used in text where paragraphs have already been broken into lines, such as certain plain text files, text sent to VT100-style terminal emulators or printers, or pages represented in page description languages. On HTML browsers supporting soft hyphens, resizing the window will re-break the above text only at word boundaries, and insert a hyphen at the end of each line.

The soft hyphen's Unicode semantics and HTML implementation are in many ways similar to Unicode's zero-width space, with the exception that the soft hyphen will preserve the kerning of the characters on either side when not visible. It becomes visible only after word wrapping at the end of a line. It serves as an invisible marker used to specify a place in text where a hyphenated break is allowed without forcing a line break in an inconvenient place if the text is re-flowed. In this context, the soft hyphen may also be called a discretionary hyphen or optional hyphen.
The use of SHY characters in text that will be broken into lines by the recipient is the application context considered by the post-1999 HTML and Unicode specifications, as well as some word-processing file formats.
