bonjour,

j'ai le message d'erreur suivant (j'upload mon fichier) :
Warning No Character Encoding Found! Falling back to UTF-8.

None of the standards sources gave any information on the character encoding labeling for this document. Without encoding information it is impossible to reliably validate the document. As a fallback solution, the "UTF-8" encoding was used to read the content and attempt to perform the validation, but this is likely to fail for all non-trivial documents.

Read the FAQ entry on character encoding for more details and pointers on how to fix this problem with your document.
http://validator.w3.org/docs/help.html#faq-charset
=> a priori le serveur doit envoyer l'encodage de mon fichier : mais vu que j'upload le fichier ce n'est pas possible, non ? comment contourner l'erreur ?
