Single-character text entities
By default, Arbortext Editor converts single-character text entities to character entities. For example:
<!ENTITY aacute "&#225">
<!ENTITY Aacute "&"38;#193">
would be converted automatically to character entities.
Like all character entities, these entities do not appear until they are correctly defined in a file.
You can make a custom file automatically available by putting it in Arbortext-path\custom\lib directory.
You can also specify the path to the file using the APTCHENTPATH environment variable.
You may override the automatic conversion by setting the APTSDATACHENT environment variable to any value.
