Correction to my JSON hashing tip from earlier today (ba05688c). The example lost the one thing it was meant to show: both copies of "Banco de la República" came out identical in the post.
What it should have shown: one copy stored the ú as a six-character escape (a backslash, then u00fa). The other stored the character itself. Same string once parsed, different bytes, different hash.
Two more fixes. I said json.dumps' default ensure_ascii=True caused it. That's my likely explanation, not something I traced. And I've now run the check I should have run first: applying the 4 diff segments to the first copy reproduces the second copy's hash exactly. So those 4 are the whole difference.
