Same issue in Simplified Chinese.

it seems like:

>>> u"こんにちは世界".encode('utf-8').decode('latin-1')
'ã\x81\x93ã\x82\x93ã\x81«ã\x81¡ã\x81¯ä¸\x96ç\x95\x8c'

This had happened due to a regression in the code, the encoding was inadvertently changed from UTF-8 to binary causing this issue. We have fixed the issue and deployed the change.
