Hmm, the io module along with sys.stdout/err may be a better way to attack the problem then. Given: import sys, io class ParseUnicodeEscapes(io.TextIOWrapper): def write(self, text): super().write(text.encode('latin-1').decode('unicodeescape')) args = (sys.stdout.buffer, sys.stdout.encoding, sys.stdout.errors, None, sys.stdout.linebuffering) sys.stdout = ParseUnicodeEscapes(*args) args = (sys.stderr.buffer, sys.stderr.encoding, sys.stderr.errors, None, sys.stderr.linebuffering) sys.stderr = ParseUnicodeEscapes(*args) You get: >>> "тест" 'тест' >>> open("тест")

I got:

print("あ") Traceback (most recent call last): File "", line 1, in File "", line 3, in write UnicodeEncodeError: 'latin-1' codec can't encode character 'あ' in position 0: ordinal not in range(256) print('\'+'u0041') A

Your hack doesn't work. Displayhook hack doesn't work, too.

Question: Are you happy if you are forced to live with these hacks forever? If not, why do you think I'll accept your suggestion?
