`read_until` is just doing a bytewise comparison. This means the following program prints `xyå12`, not `xy`, which it should if it was actually checking chars.
```rust
fn main() {
do io::with_str_reader("xyå12") |r| {
io::println(r.read_until('å', false));
}
}
```
This patch makes the type of read_until match what it is actually doing.
