    Making data 'safe' for writing to a flat file?

    The search function is throwing a 500 error, so apologies if this is covered elsewhere.

    I'm writing a small file that holds some user data and I want to ensure that I encode it so that I can read it back reliably.

    A few pieces of data could contain ANY character that could be stored in a Perl string. Also, some of these strings could be very long.

    Some example items that I would write to a file:

    NAME=Natália Braga
    CITY=São Paulo
    MEMO=This is some text. It might contain newlines, quotation marks, diacritic marks, or any other "characters" that are legal to store in a perl string.\nHow can I safely convert these data items so that I can later read them back?

    Have you looked at the encoding module?


    As you are storing personal information in a text file, it will also enable obfuscation!

    Edit-> taken from the CPAN docs
    Encoding via PerlIO

    If your perl supports PerlIO (which is the default), you can use a PerlIO layer to decode and encode directly via a filehandle.

    I would look at the functionality of the Storable module or the pack/unpack function.
