SO: the code has been broken (see post below). But I’ll still be posting the entire diary on Monday, because it’s great fun to now decipher the whole thing. I’m also in the process of transcribing the English parts of the diary. Anyone who can decipher code bits, please let me know, and I’ll add them to the English parts. That way, we can soon put the whole thing together and have the entire diary transcribed and decoded.
