# Why does a zero-width space add no visible gap?

An invisible format character that can provide a line-break opportunity. Code points: U+200B. It is not a visible space and may be rejected, ignored or exposed in some tools. A non-equivalent fallback is " " (Visible separation). Adds visible width and different wrapping behavior. Font coverage, shaping, and application acceptance were not tested, so those results are unknown.

## Code points

- U+200B ZERO WIDTH SPACE

## What was checked

### Zero-width space

An invisible format character that can provide a line-break opportunity.

It is not a visible space and may be rejected, ignored or exposed in some tools.

Remove it when unwanted; choose a visible separator if a user must see a boundary.

### Copied and still blank

This character can be copied exactly and still look blank, because it has no visible width.

A blank spot is not proof the character was dropped. A box is a different failure. Destination rendering was not tested.

Inspect the code point. Remove U+200B when a visible gap is required.

## What this does not prove

No OS, font, browser, application, field policy or rendering engine was tested. Unicode validity and segmentation do not establish actual display or acceptance.

Unicode release recorded with this answer: 18.0.0.
