Invalid character in transfer memo breaks to_json()

[cc32d9]

The memo string in this transaction causes abieos_bin_to_json to return "Extra data" error:
https://proton.bloks.io/transaction/8098be423d342f377b069fd5ee2e31aa430805aa4a7415ac451eace87fdd142e?tab=raw

Something is wrong around line 32 in include/eosio/to_json.hpp, I'm still trying to figure out.
