9ce5a835bb PyUnicode_Join() checks output length in debug mode 
PyUnicode_CopyCharacters() may copies less character than requested size, if
the input string is smaller than the argument. (This is very unlikely, but who
knows!?)

Avoid also calling PyUnicode_CopyCharacters() if the string is empty.

variables.

8cfcbed4e3 Improve string forms and PyUnicode_Resize() documentation 
Remove also the FIXME for resize_copy(): as discussed with Martin, copy the
string on resize if the string is not resizable is just fine.

a3b334da6d PyUnicode_Ready() now sets ascii=1 if maxchar < 128

4fae54cb0e In release mode, PyUnicode_InternInPlace() does nothing if the input is NULL or 
not a unicode, instead of failing with a fatal error.

Use assertions in debug mode (provide better error messages).
