-f from

Encoding source. Si n'est pas spécifié ou vaut 'detect', l'encoding est

autodétecté.

-t to

Encoding destination. Doit être spécifié.

-N Ne pas optimiser le calcul de l'encoding. Cette option n'est valide que
|
||
|
|
si -f n'est pas spécifié. On assume que tous les noms de fichiers n'ont
|
||
|
|
pas le même encoding. L'encoding from est donc recalculé à chaque fois.
