## Solution
The first part of the the message is looks like _JSFuck_, however going to that is a rabbit hole.
We see that there seems to be an "unnecessary" lines at the end. Since this problem was named __Read Between the Lines__, we do just that and see that each line has `spaces` and `tabs`.
We convert these two `0` and `1` to get the flag.
```python
found = []
with open('message') as f:
for e in f:
e = e.replace(' ', '0')
e = e.replace('\t','1')
try:
found.append(int(e,2))
except Exception:
pass
flag = []
for e in found:
try:
flag.append(chr(e))
except Exception:
break
print(''.join(reversed(flag)))
```
