No Space Between Us

There was a Discord bot that would tell "stories". The stories contained zero-width space (ZWSP), which were used to encode binary. Basically, the ZWSP was either \xe2\x80\x8c\x20 (which represented a 0), or \xe2\x80\x8d\x20 (which represented a 1).
The following script automates the process of DM-ing the bot and decoding the text.
import requests
import time
​
i = 0
​
flag = ''
​
while True:
res = ''
​
r = requests.post(
'https://discord.com/api/v9/channels/CHANNELID/messages',
headers={
'Authorization': 'TOKEN',
},
json={
"content":f"story {i}",
"tts":False
}
)
​
time.sleep(1)
​
r = requests.get(
'https://discord.com/api/v9/channels/CHANNELID/messages',
headers={
'Authorization': 'TOKEN',
}
)
​
latest = r.json()[0]
data = bytes(latest['content'], 'utf-8')
print(data)
​
low = 0
high = 4
while low < len(data):
section = data[low:high]
if section == b"\xe2\x80\x8c\x20":
res += '0'
elif section == b"\xe2\x80\x8d\x20":
res += '1'
​
low += 1
high = low + 4
​
print(res, int(res, 2), chr(int(res, 2)))
​
if flag and chr(int(res, 2)) == '}':
break
​
else:
flag += chr(int(res, 2))
​
i += 1
​
print(flag)
