Line Break - Word Joiner

Word Joiner is a special invisible character that prevents line breaks between two adjacent characters, forcing them to remain on the same line. Unlike the zero width space, which allows breaks, Word Joiner acts as a strong barrier against any automatic line breaking, even in spaces or hyphens. It is often used in technical or mathematical contexts where a line break would cause confusion, such as between a minus sign and a number, or within a multi-part identifier. The character itself has no visible width or glyph, and it does not affect spacing or kerning. Its primary function is purely typographic control, ensuring that the characters it binds stay together on a single line when text is wrapped. This makes it essential for preserving the integrity of compound terms, formulas, or any string where a break would alter meaning or readability. It does not introduce a space nor does it inhibit manual breaks, only automatic ones.
