[New-bugs-announce] [issue15379] Charmap decoding of no-BMP characters

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka at gmail.com>:

Yet one inconsistency in charmap codec.

>>> import codecs
>>> codecs.charmap_decode(b'\x00', 'strict', '\U0002000B')
('𠀋', 1)
>>> codecs.charmap_decode(b'\x00', 'strict', {0: '\U0002000B'})
('𠀋', 1)
>>> codecs.charmap_decode(b'\x00', 'strict', {0: 0x2000B})
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: character mapping must be in range(65536)

The suggested patch removes this unnecessary limitation in charmap decoder.
