[issue38755] Long unicode string causes SyntaxError: Non-UTF-8 code starting with '\xe2' in file ..., but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

[Andrew Ushakov]

New submission from Andrew Ushakov <andrew.ushakov at gmail.com>:

Not very long unicode comment #, space and then 170 or more repetitions of the utf8 symbol ░ (b'\xe2\x96\x91'.decode()) 

# ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░

causes syntax error:

SyntaxError: Non-UTF-8 code starting with '\xe2' in file tst112.py on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

Python file is attached. Second example is similar, but here unicode string with similar length is used as an argument of a print function.

print('\n░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░')
