Hi,

I have this funny looking JSON:
js='{"subject":"\xc3\x9aj tev\xc3\xa9kenys\xc3\xa9g a vide\xc3\xb3ddal kapcsolatban: UGORJ M\xc3\x81R!!! / Yellow : The Yellow Artifact","snippet":"\xc3\x9aj tev\xc3\xa9kenys\xc3\xa9g a vide\xc3\xb3ddal kapcsolatban: Videos DB megjegyz\xc3\xa9st \xc3\xadrt ehhez: \\r\\nUGORJ M\xc3\x81R!!! / Yellow : The Yellow Artifact nem t\xc3\xb6lt le a szaros Evolve \\r\\nStage\\uD83D\\uDE24\\uD83D\\uDE26\\uD83D"}'

I can json.loads this from CPython, and can't from pypy:
