[New-bugs-announce] [issue26754] PyUnicode_FSDecoder() accepts arbitrary iterable

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

PyUnicode_FSDecoder() accepts not only str and bytes or bytes-like object, but arbitrary iterable, e.g. list.

Example:

>>> compile('', [116, 101, 115, 116], 'exec')
<code object <module> at 0xb6fb1340, file "test", line 1>

I think accepting arbitrary iterables is unintentional and weird behavior.
