[New-bugs-announce] [issue28350] Interning string constants with null character

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Currently string constants are interned if they consist of ASCII word characters ([0-9A-Za-z_]). But strings are tested only to the first null character. This is not problem for names, since they can't include null characters, but string constants that contains ASCII non-word characters after the null character passes this test.

Proposed simple patch fixes the testing function all_name_chars().

Other question: shouldn't PyUnicode_IsIdentifier() be used in 3.x?
