you do have to be a bit careful with utf-8, as many possible byte
sequences map down to the same rune (error), so if you
do your comparisons too early, you run the risk of inconsistency.
for instance, you can exploit this (at least, i *think* this is the
cause) to create a file that can never be removed on ken's fileserver:
#include <u.h>
#include <libc.h>
void
main(void)
{
char f[] = {0xc0, 0xb0, 0};
create(f, OWRITE, 0666)
}
don't try this at home...
