Hello,J'ai créé un transformer personnalisé comme expliqué plus haut. Cela fonctionne avec les message UTF-8 (Content-Type: text/plain; charset=UTF-8) mais pas avec les autres types (par exemple: Content-Type: multipart/alternative; boundary="—-=_NextPart_000_00E3_01CC2B6A.D7002360").Est-ce possible d'avoir un aperçu avec des accents pour tous types d'emails ?Transformer utilisé :import java.io.InputStream;

J'ai aussi testé le code qui est actuellement sur le SVN (https://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/HEAD/root/projects/repository/source/ja...) . Je pensais qu'il était générique car il prend en compte l'encoding (reader.getEncoding()). Cependant cela ne va pas mieux (voir pire car les accents en UTF-8 ne sont pas gérés). J'ai tenté un mix des 2 méthodes… ok pour UTF-8 mais tous les mails ne sont pas bien traités… :
logger.debug("Working…");
is = reader.getContentInputStream();
EncodingManager encodingManager = new EncodingManager();
transformer.getFont().setEncoding(encodingManager.getEncoding(COSName.WIN_ANSI_ENCODING));
ir = buildReader(is, reader.getEncoding(), reader.getContentUrl());
pdf = transformer.createPDFFromText(ir);
// dump it all to the writer
os = writer.getContentOutputStream();
pdf.save(os);
Merci bien.
