Yes, i'm thinking about that...
If i choose "default",
With CSV i have a UTF-8 (opened with open office)
With EXCEL CSV i have UTF-16, but i have 3 character undesired at the beginning
Don't see it before, but don't remember if i used the default settings...
I will do some others tests.
Perhaps safe code is to add an option for chose iconv or not (and in this case use the old code)?
