in thread convert files to ansi (8859-1)

You cannot read octets from a file and then hope that Perl will know that you meant UTF-8. You always have to decode your input and encode your output.

    Maybe we talk past each other?

    My utf8 to iso-8859-1 should do the following:
    - read file into scalar
    - eval decode utf8
    -- if we get an error, then i simply say it's iso-8859-1 and I don't do anything
    -- it we get no error, then i use the decoded string

    On the other script iso-8859-1 to utf8, I wanna go the same way:
    - read file into scalar
    - eval decode iso-8859-1
    -- if we get an error, then i simply say it's utf8 and I don't do anything
    -- it we get no error, then i use the decoded string

    Now I expect we get an eval decode iso-8859-1 error if the input file is utf8, but I don't.

      That's wrong.

      If your input is bytes that are a valid UTF-8 sequence, you still need to call decode on it to have usable strings in Perl.

        Okay. So perl works internal using single-byte code?

        But why does eval decode iso-8859-1 don't throw an error if the input file is utf8?
