[issue39109] [C-API] PyUnicode_FromString

[STINNER Victor]

STINNER Victor <vstinner at python.org> added the comment:

> I think the ob_refcnt Field should be 1 in both cases. Or why is the refcnt here so high?

Python has singletons for short strings: empty string and 1-character latin1 characters (unicode range [U+0000; U+00FF]).

Examples:

>>> sys.getrefcount("")
103
>>> sys.getrefcount("a")
11

It's not a bug, but an optimization to reduce the memory footprint ;-)
