A raw content format is a system of converting data to displayable information. For adequate treatment in plain text, symbols must also be displayable in a monochromatic setting. This representation is then rendered as a displayable image. ASA control characters are all displayable characters. In visual browsers, displayable elements can be rendered as either "block" or "inline". Software then uses this data to create displayable 2D or 3D images. OpenDocument version 1.2 fully describes mathematical formulas displayable on-screen. Since this row is not displayable it does not interfere with normal pages.
