Unfortunately this won't work since the shell is responsible
for expanding the ? and * wildcard characters, not the kernel
(just for fun, consider implementing a shell which used different
wildcard characters...it's only confusing to the user).

Try this:

main()
{
	unlink("\177\177\177H01.b");
}

It also might be worth using "od" to examine the directory...if
the high order bit is on in any of the bytes in the file name, then
the shell won't show them (since most shells strip the high order
bit).  If that's the case, then you would need to use:

main()
{
	unlink("\377\377\377H01.b");
}
