New submission from Serhiy Storchaka:
An error handler in unicode_escape_decode() eats at least one byte (or more)
after illegal escape sequence.
>>> import codecs
>>> codecs.unicode_escape_decode(br'\u!@#', 'replace')
('�', 5)
>>> codecs.unicode_escape_decode(br'\u!@#$', 'replace')
('�@#$', 6)
raw_unicode_escape_decode() works right:
>>> codecs.raw_unicode_escape_decode(br'\u!@#', 'replace')
('�!@#', 5)
>>> codecs.raw_unicode_escape_decode(br'\u!@#$', 'replace')
('�!@#$', 6)
