Defining Non-Default Characters as Character Entities
To use words and phrases from a language other than the language of your native authoring environment when that language contains characters not in the default system alphabet, use character entities. They must be defined using entity declarations in your DTD or in a document's own internal subset.
You can also use parameter entities to define character entities for an entire ISO character set with just one entity declaration. Parameter entities — referencing entity declaration files in the Arbortext Editor online help describes this process.
1. Insert the desired entity declaration(s) in the DTD. There are two ways to do this:
◦ Insert individual character entities, one for each character you need.
◦ Insert a single parameter entity to reference an Arbortext Editor.gml file which contains the entity declarations for an entire character set.
This table shows which .gml file to use for a given character set:

2. For each .gml file you reference in your DTD with a Public Identifier, make an entry in your catalog file.
3. Optional: Map key combinations for your character entities. There are already key combinations for the ISO 8859–1 and –2 (ISO Latin 1 and 2) character sets. See Keyboard shortcuts in the Arbortext Editor online help for the keyboard shortcuts for these characters.

In addition to the .gml files required for language support, you might want to have an entity declaration in your DTD referencing the iso-num.gml file. This gives you character entities for many special characters such as the yen (¥), pound (£), and copyright (©) symbols.
