New submission from Florent Xicluna <florent.xicluna at gmail.com>:

from io import BytesIO
from tokenize import tokenize, tok_name

sample = 'éléphants = "un éléphant, deux éléphants, ..."\nprint(éléphants)\n'
sampleb = sample.encode('utf-8')

exec(sample)
# output: un éléphant, deux éléphants, ...
exec(sampleb)
# output: un éléphant, deux éléphants, ...

module = BytesIO()
module.write(sampleb)
module.seek(0)

for line in tokenize(module.readline):
    print(tok_name[line.type], line)


# output:
