Wouldn't it be nice if people knew what the desired output was? I can see a long, unstructured (?) sequence of "u1u1"s and long runs of spaces, interspersed with single characters from the original filename. jim mcnamara is certainly right when suspecting all this can be done with one awk, but who knows HOW that would / should be achieved?

And, the resulting "identifier" is 1199 char long - may work in some proprietary systems, but will certainly not be manageable for e.g. file names' in all *nix file systems.
Did you notice that $WIDTHA does NOT represent the file name's length but is one larger?

NAME
convertfs - convert an HFS file system to allow long file names SYNOPSIS
[special-file] DESCRIPTION
The command converts an existing HFS file system supporting the default maximum file name length of 14 characters into one that supports file names up to 255 characters long. Once an HFS file system is converted to long file names, it cannot be restored to its original state, since the longer file names require a directory representation that is incompatible with the default HFS directory format. Since this is an irreversible operation, prompts for verification before it performs a conversion. forces the system to reboot if the root file system is converted. When converting the root file system, the system should be in single- user mode, with all unnecessary processes terminated and all non-root file systems unmounted. Except for the root file system, requires that the file system to be converted be unmounted. If invoked without arguments, interactively prompts the user with a list of the HFS file systems from One or more or all of the listed file systems can be selected for conversion. Typically, it is desirable to convert all of the file systems in to avoid inconsistencies between two file systems mounted on the same system. can also be invoked with an argument of either a block or character special-file name for a file system to be converted. Only the block special file should be specified for a mounted root file system. As part of the conversion process, performs an on each file system (see fsck(1M)). Options Do it quietly. will perform the conversions without querying the user. Normally prompts the user before converting a file system. RETURN VALUE
returns the following values: Success. Either successfully converted the file system, or the file system already allowed long file names. Failure. was not able to convert the file system due to some failure in processing. AUTHOR
