Case "S" (type str): "%s" uses _PyObject_Str() which checks the object type with PyString_CheckExact(). Case "U" (type unicode) "%s" uses PyUnicode_Check() and then calls PyUnicode_Format(). PyUnicode_Format() uses PyUnicode_Check() to check the object object. It should uses PyUnicode_CheckExact() instead. xxx_CheckExact() is different than xxx_Check(): exact is only true for the base type, whereas the the second is also true for subclass. |

Patch: Use PyUnicode_CheckExact() instead of PyUnicode_CheckExact() in PyUnicode_Format() to use obj.__unicode__ slot. |
