Insert special characters

You can insert certain special characters (line breaks, soft hyphens, nonbreaking spaces, and em dashes) in a tagged PDF to improve the way it reflows. You can also insert these special characters in any PDF to improve the way it’s read by a screen reader or simply to edit it for general readability purposes. You do not need to have the font installed in order to insert special characters.

1. Select the TouchUp Text Tool.
2. Click where you want to insert the character, or select text to be replaced by the character.
3. Right-click/Control-click the selected text or location, choose Insert and then select an option.
