Hmm, looking at the hexdump reminded me of something that happened in my AMIGA heydays...
Because you quoted that file dates back to 1992 maybe instead of each 'NUL' character being decoded as a UNICODE, they are a single byte ONLY.

I suspect that each 'NUL' is not 0xE2 0x90 0x80 but is in fact ONLY 0x00 with the top bit set giving 0x80 and they are being interpreted as UNICODE characters.
I have no idea if this would work but this might work in bash:
Code:
namestart=$'\x80\x80'
rm -rf "${namestart}"*

This could even apply to the (R) and TM characters as well.
Just a lateral thought.

UTF8(5) 						      BSD File Formats Manual							   UTF8(5)

NAME
utf8 -- UTF-8, a transformation format of ISO 10646 SYNOPSIS
ENCODING "UTF-8" DESCRIPTION
The UTF-8 encoding represents UCS-4 characters as a sequence of octets, using between 1 and 6 for each character. It is backwards compatible with ASCII, so 0x00-0x7f refer to the ASCII character set. The multibyte encoding of non-ASCII characters consist entirely of bytes whose high order bit is set. The actual encoding is represented by the following table: [0x00000000 - 0x0000007f] [00000000.0bbbbbbb] -> 0bbbbbbb [0x00000080 - 0x000007ff] [00000bbb.bbbbbbbb] -> 110bbbbb, 10bbbbbb [0x00000800 - 0x0000ffff] [bbbbbbbb.bbbbbbbb] -> 1110bbbb, 10bbbbbb, 10bbbbbb [0x00010000 - 0x001fffff] [00000000.000bbbbb.bbbbbbbb.bbbbbbbb] -> 11110bbb, 10bbbbbb, 10bbbbbb, 10bbbbbb [0x00200000 - 0x03ffffff] [000000bb.bbbbbbbb.bbbbbbbb.bbbbbbbb] -> 111110bb, 10bbbbbb, 10bbbbbb, 10bbbbbb, 10bbbbbb [0x04000000 - 0x7fffffff] [0bbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb] -> 1111110b, 10bbbbbb, 10bbbbbb, 10bbbbbb, 10bbbbbb, 10bbbbbb If more than a single representation of a value exists (for example, 0x00; 0xC0 0x80; 0xE0 0x80 0x80) the shortest representation is always used. Longer ones are detected as an error as they pose a potential security risk, and destroy the 1:1 character:octet sequence mapping. SEE ALSO
