Stores the names of alternative fonts that can be used when a requested font or a font that appears in a document either is not available or is unsupported.
Entries in this subkey are of data type REG_SZ and are named after the fonts for which substitutes are defined. The value of an entry is the name of the font to be used in substitution for the font name matched by the name of the entry. For example, the entry Helvetica, if it exists in the registry, could store the string "Arial", which would configure Arial as a substitute for Helvetica.
