## Fold Characters Substitutions

The Re-encode statement's Fold Characters mode replaces various Unicode characters with their ISO-8859-1 equivalents. The following substitutions are by default performed:

Grave accent1 | ` | 60 | Apostrophe | ' | 27
Acute accent1 | ´ | B4 | Apostrophe | ' | 27

1. While this is a valid ISO-8859-1 character, it's standalone usage is in practice typically used to represent a single quote.

You can replace or add to the default substitutions by creating a Replacement Set which has been given the special Fold Character status (F). If a Replacement Set with the special Fold Character status can be located its contents will be used to define the transformations. If such a set cannot be found, the default values displayed in the above table will be used.

If you wish to create a set with the built in substitutions to start with, you can do so via the Create a Set With the Default Fold Character Values context menu item. Note that the created set will not automatically be supplied the special Fold Character status.

When analyzing the fold character replacement set, the following applies:

- Each from field can contain as many replacement characters as desired. Spaces are ignored. Therefore you can enter multiple characters for the same replacement value on the same item if you desire.
- The to field may be empty and spaces are significant.
- There is no implied order to the transformations.
