Thank you Tshering, yes is a part of description of my problem.
I do not know it but I listen for the Council.
I've done with notepad + my text is in UTF8, but I saved my files in utf8 names.
I work with windows, I don't know unix, I do not know programming.
All my file names éa éb ...... ûm html are windows character.
I read

the text 7-zip.chm to try to understand, its difficult for me.
