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.

NAME
utf2 -- Universal character set Transformation Format encoding of runes SYNOPSIS
ENCODING "UTF2" DESCRIPTION
The UTF2 encoding has been deprecated in favour of UTF-8. New applications should not use UTF2. The UTF2 encoding is based on a proposed X-Open multibyte FSS-UCS-TF (File System Safe Universal Character Set Transformation Format) encod- ing as used in Plan 9 from Bell Labs. Although it is capable of representing more than 16 bits, the current implementation is limited to 16 bits as defined by the Unicode Standard. UTF2 representation is backwards compatible with ASCII, so 0x00-0x7f refer to the ASCII character set. The multibyte encoding of runes between 0x0080 and 0xffff consist entirely of bytes whose high order bit is set. The actual encoding is represented by the following table: [0x0000 - 0x007f] [00000000.0bbbbbbb] -> 0bbbbbbb [0x0080 - 0x07ff] [00000bbb.bbbbbbbb] -> 110bbbbb, 10bbbbbb [0x0800 - 0xffff] [bbbbbbbb.bbbbbbbb] -> 1110bbbb, 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 (but the longer ones will be correctly decoded). The final three encodings provided by X-Open: [00000000.000bbbbb.bbbbbbbb.bbbbbbbb] -> 11110bbb, 10bbbbbb, 10bbbbbb, 10bbbbbb [000000bb.bbbbbbbb.bbbbbbbb.bbbbbbbb] -> 111110bb, 10bbbbbb, 10bbbbbb, 10bbbbbb, 10bbbbbb [0bbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb] -> 1111110b, 10bbbbbb, 10bbbbbb, 10bbbbbb, 10bbbbbb, 10bbbbbb which provides for the entire proposed ISO-10646 31 bit standard are currently not implemented.
