= ASCII art TODO
{c}

The following almost certainly contain ASCII art but we were not yet able to decode them. Puzzle solvers from the Internet, we need your help!

The Bitcoin message is acknowledged on the website at:
  \Q[archiviert auf der BTC Blockchain TX b8e80f2bd1eac8c6db4dfb8b6cc9c8eb71133cbc1a0d32e6952c1a2818eecc8f]
  She apparently lived in Germany as the website is bilingual German/Chinese, the text:
  \Q[Wir vermissen dich]
  means:
  \Q[We miss you]
  TODO decode properly. It is encoded as <P2PKH> keys (20 bytes at a timt) but also contains its own newlines and trailing spaces. Maybe a start:
  ``
            .-==-.
            `-==-
             |    |
             |    |
             |
        Yang, Yiping
       '~~~~~~~~~~~~~~~~~~'
       *-====-.    .-====-*
       *~~~~~~~~~~~~~~~~~~*
       .-====='    '=====-.
       .~~~~~~~~~~~~~~~~~~.
       //yang.yiping.de/btc
       Wir vermissen dich! |
            Yang, Yiping   |~

  Could it be across? She's apparently <Christian> based on the website.

Perhaps they are meant to be assembled together somehow?

Each line is encoded with <OP_RETURN>, is 38 bytes long, and starts and ends in 6 spaces, leading to 26 non-whitespace characters per line. In block order we have:

  seem like <Base64> encoded data due to the `=` sign padding, but nothing human readable comes out of them.
