Ah. Thanks for that. I've changed that script to:

perl -i -pe 'BEGIN{binmode STDOUT,":encoding(utf16le)"; undef $/;} s/\xFF\xFE/\xFF\xFEFilename:$ARGV\n/' `find . -name '*.TXT'`

however have since discovered that simply writing my new code over the BOM of the original data solved my problem:

perl -i -pe 'BEGIN{undef $/;} s/\xFF\xFE/Filename:$ARGV\n/' `find . -name '*.TXT'`

I'm not sure if this is because my source data might actually be mixed utf8 and utf16le. In summary then - I don't think I've actually solved outputting in utf-16LE however I have solved my issue at present. Thanks very much to your reply and many of the other posts on this site which helped me comprehend this. Any other tips welcome.
