Modifier la police uniquement pour certains caractères Unicode lors de l enregistrement en PDF avec JavaScript via C++

Exemple

La capture d’écran suivante compare les deux fichiers PDF générés par le code d’exemple ci-dessous.

L’un est généré sans définir la propriété PdfSaveOptions.isFontSubstitutionCharGranularity et l’autre après avoir défini cette propriété sur vrai.

Comme vous pouvez le voir dans le premier PDF, la police de la phrase entière a changé de Times New Roman à Arial Unicode MS à cause du tiret non sécable. Dans le second PDF, seule la police du tiret non sécable a changé.
