IMHO a glob match returns even unprintable characters.
So the last proposal does not improve anything.

And the clri command (didn't know it yet), will cause extra harm.
It is useless to clear the inode of the file, because an inode contains the data block structure and all meta information BUT THE FILENAME.
The filename and the pointer to the inode is stored in the directory.
The directory is another inode. To have an effect you must clear the directory inode.
I expect less damage with

Code:

unlink <directory>

if supported by the OS. If successful, you need a full file system check, in order to collect the dangling file inode and its data blocks.
I successfully did that a couple of times on a non-journaling UFS in single-user mode (no desktop, no other processes running).

I would go for a disk editor. Find the offending name, compare the shown bytes with the characters from the ls command, change one byte, save, compare again, ...

clri

CLRI(8) 						    BSD System Manager's Manual 						   CLRI(8)

NAME

     clri -- clear an inode

SYNOPSIS

     clri special_device inode_number ...

DESCRIPTION

     Clri is obsoleted for normal file system repair work by fsck(8).

     Clri zeros out the inodes with the specified inode number(s) on the filesystem residing on the given special_device.  The fsck(8) utility is
     usually run after clri to reclaim the zero'ed inode(s) and the blocks previously claimed by those inode(s).  Both read and write permission
     are required on the specified special_device.

     The primary purpose of this routine is to remove a file which for some reason is not being properly handled by fsck(8).  Once removed, it is
     anticipated that fsck(8) will be able to clean up the resulting mess.

SEE ALSO

     fsck(8), fsdb(8), icheck(8), ncheck(8)

BUGS

     If the file is open, the work of clri will be lost when the inode is written back to disk from the inode cache.
