I use Win XP, notepad text editor and IM 6.4.1.
I found why accents were not processed under the -annotate coomand:
it comes from notepad text editor. When editing accent characters such as é, è, ù, ... into the command line these characters are not saved properly because notepad is a 7 bits editor. It replaces them by wrong characters. The solution is to edit 8 bits characters using ALT+[decimal value of the character to edit], and it works straight!
PS: it does not work when saving the txt file under unicode coding format because notepad adds control characters which IM do not understand.
