NAME

Encode::Safename - An encoding for safe filenames.

VERSION

Version 0.05

SYNOPSIS

An encoding to encode filenames to safe filenames, that is filenames that are valid on all filesystems.

use Encode qw(decode encode);
use Encode::Safename;

$encoded = encode('safename', 'Foo Bar Baz.txt');
# $encoded is now '{f}oo_{b}ar_{b}az.txt'
$decoded = decode('safename', $encoded);
# $decoded is now 'Foo Bar Baz.txt'

DESCRIPTION

A filename is encoded as follows:

  • A range of uppercase characters is changed to lowercase characters, and put between braces.

    'F'   -> '{F}'
'FOO' -> '{foo}'

  • A range of spaces is changed to underscores.

    ' '   -> '_'
'   ' -> '___'

  • A range of safe characters (characters that are valid on all filesystems, excluding braces, parentheses, and underscores) is left unchanged.

    'f'   -> 'f'
'foo' -> 'foo'

  • All other characters are changed to their Unicode codepoint in hexadecimal notation, and put between parentheses.

    ':'  -> '(3a)'
':?' -> '(3a)(3f)'

Combined, this gives the following:

'FOO: Bar Baz.txt' -> '{foo}(3a)_{b}ar_{b}az.txt'
