set composedcharactersubstitution= { on | off}

This option specifies whether the publishing engine will replace some ASCII characters with their typographical equivalents.

When composedcharactersubstitution is set to on, the characters get replaced by their typographical equivalents as described in the example. The replacements happen for elements that do not have the allowCharacterSubstitution control set to off in the .dcf file.

When composedcharactersubstitution is set to off (the default), ASCII characters are never replaced in any context.

Replacements never occur when publishing using XSL-FO.
