Cwd::utf8 - Fully UTF-8 aware Cwd


version 0.011


    # Using the utf-8 versions of cwd, getcwd, fastcwd, fastgetcwd
    use Cwd::utf8;
    my $dir = getcwd;

    # Using the utf-8 versions of abs_path
    use Cwd::utf8 qw(abs_path);
    my $abs_path = abs_path($file);

    # Exporting no functions
    use Cwd::utf8 qw(:none); # NOT "use Cwd::utf8 qw();"!
    my $real_path = Cwd::real_path($file);


While the original Cwd functions are capable of handling UTF-8 quite well, they expects and return all data as bytes, not as characters.

This module replaces all the Cwd functions with fully UTF-8 aware versions, both expecting and returning characters.

Note: Replacement of functions is not done on DOS, Windows, and OS/2 as these systems do not have full UTF-8 file system support.


The module behaves as a pragma so you can use both use Cwd::utf8 and no Cwd::utf8 to turn utf-8 support on or off.

By default, cwd(), getcwd(), fastcwd(), and fastgetcwd() (and, on Win32, getdcwd()) are exported (as with the original Cwd). If you want to prevent this, use use Cwd::utf8 qw(:none). (As all the magic happens in the module's import function, you can not simply use use Cwd::utf8 qw())



By default Cwd:::utf8 marks decoding errors as fatal (default value for this setting is Encode::FB_CROAK). If you want, you can change this by setting Cwd::utf8::UTF8_CHECK. The value Encode::FB_WARN reports the encoding errors as warnings, and Encode::FB_DEFAULT will completely ignore them. Please see Encode for details. Note: Encode::LEAVE_SRC is always enforced.


Please report any bugs or feature requests on the bugtracker website.

When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature.


The filesystems of Dos, Windows, and OS/2 do not (fully) support UTF-8. The Cwd function will therefore not be replaced on these systems.


  • Cwd -- The original module

  • File::Find::utf8 -- Fully utf-8 aware versions of the File::Find functions.

  • utf8::all -- Turn on utf-8, all of it. This was also the module I first added the utf-8 aware versions of Cwd and File::Find to before moving them to their own package.
