The last solution use newline characters, so the `\n`s should be replaced by linefeeds. These solutions are mostly helped by Raku's unicode operators and digits, as well as being able to convert from lists or strings to numbers freely, where lists are equal to their length.

𑄸𑄻𑄼

These are all numeric literals of 256 in different unicode digits (with no bytes overlapping). Yes, Raku supports this. No, I don't know why.

### 8. 
~~~
4⁴
~~~

Four to the power of 4

### 9.
~~~
0x100
~~~

Hexadecimal of 256

### 10.
~~~
ord
Q`Ā`
~~~

Get the ordinal value of the 256th character.


### 11.
~~~
'~~~'~^'LKH'
~~~

String xor `~~~` with `LKH` to get 256.

### 12.
~~~
888-88-88-88-88-88-88-88-8-8
~~~

Some basic arithmetic to get 256

### 13.
~~~
99+99+9+9+9+9+9+9+?9+?9+?9+?9
~~~

More arithmetic, using `?` to boolify 9 to True, which then is numerically 1.

### 14.
~~~
($_=3333333)&&m|(3)(3)(3)(3)*|&&$3**$3
~~~

Set `$_` to 3333333, then match some 3s such that the fourth group is of length 4, then return that group to the power of itself (`4**4`). This one might be a little iffy, since it relies on the existing `$_` variable to be mutable, (which it is by default).

### 15.
~~~
[[];[];[];[]]×[[];[];[];[]]×[[];[];[];[]]×[[];[];[];[]]
~~~

Make a list of length 4 and multiply it by itself four times.

### 16.
~~~
"{"{7%%7%7}{7%7}7"%7}{"{7%%7%7}{7%%7%7}7"%7}{"{7%%7%7}{7%%7%7}{7%%7%7}"%7}"
~~~

Uses modulo and divisibility operators with string interpolation to generate numbers.

~~~
  "{"{1}{0}7"%7}{"{1}{1}7"%7}{"{1}{1}{1}"%7}"
= "{2}{5}{6}"
= 256
~~~ 

### 17.
~~~
</ / ... / />/</ />
~~~

Create a list with length 512 and divide it by a list with length 2.

### 18.
~~~
q:w!a
a
...
a
a!.Int
~~~

Create a list of length 256 using the words quoting construct and then convert it to an integer.


### Conclusion

I can certainly save some characters from some solutions to use later, but I've sort of run out operators that can convert them to numbers. I still have carriage returns for whitespace, so maybe there's a function I can still use.
