Correction & Decoration

luatex-cn provides tools for classical text correction and decoration, including correction marks, emphasis marks, and underlines (proper name marks / book title marks).

Correction (GaiZi)

The \fix (or \改) command marks corrections in classical text editing. It retains the original character with a deletion mark (、) and places the replacement character at the bottom right.

Usage

\fix{replacement}
% or Chinese alias
\改{替换字}

Example

This has a \fix{correct}wrong text.

In this example, "wrong" is marked with a deletion symbol, and "correct" is placed at its bottom-right corner at 60% size.

Technical Details

• Deletion Mark: Automatically overlays a deletion point (、) on the character.
• Replacement Text: Placed at bottom-right corner at 60% of original font size.
• Non-destructive: Does not affect the original grid layout.
