The hyphenate-character CSS property sets the character (or string) used at the end of a line before a hyphenation break.
Both automatic and soft hyphens are displayed according to the specified hyphenate-character value.
Syntax
hyphenate-character: <string>; hyphenate-character: auto;
The value either sets the string to use instead of a hyphen, or indicates that the user agent should select an appropriate string based on the current typographic conventions (default).
Values
- <string>
- 
    The <string>to use at the end of the line before a hyphenation break. The user agent may truncate this value if too many characters are used.
- auto
- 
    The user-agent selects an appropriate string based on the content language's typographic conventions. This is the default property value, and only needs to be explicitly set in order to override a different inherited value. 
Formal definition
| Initial value | auto | 
|---|---|
| Applies to | text | 
| Inherited | yes | 
| Computed value | specified keyword | 
| Animation type | discrete | 
Formal syntax
auto | <string>
Examples
  This example shows two identical blocks of text that have hyphens set to ensure that they break wherever needed, and on soft hyphen breaks (created using ­).
  The first block has the value of the hyphen changed to the equals symbol ("=").
  The second block has no hyphenate-character set, which is equivalent to hyphenate-character: auto for user agents that support this property.
