Note below how ã changes to a. NOTE2: Before you blame this on CMD.EXE and Windows pipe weirdness, see Experiment 2 below which gets a similar problem using File::Find.

The particular problem I'm trying to fix involves working with image files stored on a local drive, and manipulating the file names which may contain foreign characters. The two experiments shown below are intermediate debugging steps.

The ã character is common in latin languages. e.g. http://pt.wikipedia.org/wiki/Cão

Experiment 1

alt text

Experiment 2

To get around my particular problem, I tried using File::Find instead of piped input. The issue actually gets worse: alt text

Debugging update:

I tried some of the tricks listed at http://perldoc.perl.org/perlunicode.html, e.g. use utf8, use feature 'unicode_strings', etc, to no avail.
