[New-bugs-announce] [issue43340] json.load() can raise UnicodeDecodeError, but this is not documented

[Matthew Woodcraft]

New submission from Matthew Woodcraft <matthew at woodcraft.me.uk>:

The documentation for json.load() and json.loads() says:

« If the data being deserialized is not a valid JSON document, a JSONDecodeError will be raised. »

But this is not currently entirely true: if the data is provided in bytes form and is not properly encoded in one of the three accepted encodings, UnicodeDecodeError is raised instead.

(I have no opinion on whether the documentation or the behaviour should be changed.)
