About:
convmv converts filenames (not file content), directories, and even whole filesystems to a different encoding. This comes in very handy if, for example, one switches from an 8-bit locale to an UTF-8 locale or changes charsets on Samba servers. It has some smart features: it automagically recognises if a file is already UTF-8 encoded (thus partly converted filesystems can be fully moved to UTF-8) and it also takes care of symlinks. Additionally, it is able to convert from normalization form C (UTF-8 NFC) to NFD and vice-versa. This is important for interoperability with Mac OS X, for example, which uses NFD, while Linux and most other Unixes use NFC. Though it's primary written to convert from/to UTF-8 it can also be used with almost any other charset encoding. Convmv can also be used for case conversion from upper to lower case and vice versa with virtually any charset. Note that this is a command line tool which requires at least Perl version 5.8.0.

[»] UTF-16 and convmv 1.10
by Roc Vallès Domènech - Dec 7th 2007 01:32:25

I have a bunch of UTF-16 files (from windows-made zips) to convert, and I'm having no luck with 1.10, as it follows:

$ convmv -f UTF-16 -t UTF-8 /bin/ls
Starting a dry run without changes...
UTF-16:Unrecognised BOM 6c73 at /usr/lib/perl5/5.8.8/i686-linux/Encode.pm line 186.

UTF-16 is the *internal* charset of windows filesystems. You never see UTF-16 in filenames externally. You cannot use that charset as it contains null bytes, which are not alloowed in filenames. Please read the man page to get more information on all that stuff.

[»] convmv for win32?
by asfaltboy - Jan 3rd 2007 02:12:09

Have anyone heard of the same solution for converting filename encoding in windows? I'm having a really hard time finding something...

I haven't, I'm afraid.

I don't even know how to find out what the encoding of filenames on Windows is.
Anyone?

I believe Windows' NTFS filesystem uses UTF-16.

[»] Problem with Perl 5.8.7 (Encode 2.10)
by Björn JACKE - Dec 5th 2005 03:54:04

Perl 5.8.7 (Encode 2.10) has a changed decode_utf8() function, which makes convmv think *all* files are already UTF-8 encoded. This is a misbehaviour of Perl and the docs describe a different behaviour. Don't use Perl 5.8.7 with convmv, this will hopefully be fixed in newer Perl releases.

This is being worked around in release 1.09 now.
