I don't have any issue with "find" from the GNU findutils:

.
./file?[H?[c??

FYI, this was fixed in 2005 after I reported the problem with
non-printable characters:

Still no issues:

rm: descend into directory 'emptydir'? y
rm: remove regular empty file 'emptydir/file'$'\033''[H'$'\033''[c'$'\n\b'? y
rm: remove directory 'emptydir'? y

with "rm" from the GNU coreutils 9.10.
