Enregistrer la feuille au format TXT avec codage UTF-8

Question

Je travaille à l'écriture d'un script pour la génération de rapports nécessitant un format de ligne de 80 octets.
Actuellement, mon script formate correctement tous les champs, les concatène en une seule colonne et supprime le reste. Cette colonne concaténée comporte des espaces séparant les champs qui ne peuvent pas être supprimés lors de leur sauvegarde. Tout cela est fait sur une version 64 bits d'Excel 2016 sur Windows 10.
Comment sauvegarder le fichier sous forme de fichier texte codé en UTF-8?

Answer 1

J'ai fini par écrire un script AHK qui ouvre Notepad ++, modifie le codage, enregistre le fichier et le ferme. Pas aussi élégant que je l'aurais espéré, mais ça fait le boulot.
