Using Custom list with some filenames causes error

[Laura]

Using 7zip default context item to compress files with other characters
example:.... "Çüéâä",
operation finished with success,
but if i compress same files using custom list causes error.

7zG a -tzip archive.zip @listfile.txt

Are accepted Only ASCII code from 01 to 126 ( except: 07 - 15 - 20 - 21 )
all other character from ASCII 127 to 255, causes
This advise: "incorrect item in list file" (example ASCII character code 174 - 175)
or block compression job (example ASCII character code 127..155)

Have you some suggestion to give me please ?

-scs{WIN|DOS|UTF-8} specifies charset for list files.
Default charset for list files is UTF-8.

very Good! All done. :-)
Thank you very much for rapid answer.

Also if is off Topic i ask you also this:

Searching on WEB and fourms for solution i have found this guide : http://www.nanoant.com/programming/themed-menus-icons-a-complete-vista-xp-solution

that explain how integrate an icon to context menu, because into actual version of 7zip is absent and it is very easy and immediately found 7zip program into context from lots other programs present into list, if its icon is showed, but unfortunately this guide it too difficult for me in order to realize this purpose.

Do you know if exists some custom script that permit me to add all 7zip options icons to context ?
Thanks again and sorry for disturb.
