(BTW, you might find it easier to use the perl built-in function "rename" -- it saves you from worrying about what happens to non-ASCII data being passed as command-line args to a sub-shell.)

Yeah, instead of worrying about what happens if you do a system call, you now have to worry about what happens if you do a system call. The same thing happens: latin1 or utf8 encoding may be used, depending on the circumstances. Thus: encode explicitly.

    Thank you all for your responses.

    Juerd, I am wondering what you mean when you keep saying "encode explicitly":

    The unicode strings I am trying to set as the filename are encoded as utf8 from a web form. They go into the utf8-character-set encoded mysql database. They display properly on the web form. What step for encoding explicitly could I be missing? It seems to me that they begin life as utf8 and they stay that way. How do I get more explicit?

      Juerd, I am wondering what you mean when you keep saying "encode explicitly":

      Perhaps it is time to read the Perl Unicode Tutorial :-).

      If they began life as utf8, they do indeed very probably stay that way if you do nothing to them, but if that were the case, I think you might not have been asking the question that you have.

      Encoding explicitly means to use encode() or encode_utf8(), in this case. It would also require that the values coming from the database are decoded at some point. The DBD::mysql module can do this for you. I don't know if it is.
