Description:

Convmv is meant to help convert a single filename, a directory tree
and the contained files or a whole filesystem into a different
encoding. It just converts the filenames, not the content of the
files. A special feature of convmv is that it also takes care of
symlinks, also converts the symlink target pointer in case the symlink
target is being converted, too. All this comes in very handy when one
wants to switch over from old 8-bit locales to UTF-8 locales. It is
also possible to convert directories to UTF-8 which are already partly
UTF-8 encoded. Convmv is able to detect if certain files are UTF-8
encoded and will skip them by default. To turn this smartness off use
the "--nosmart" switch.
