New submission from Serhiy Storchaka: Currently PyUnicode_FromFormat doesn't check an argument for %c and can raise SystemError only due maxchar check in PyUnicode_New. On 2.7 an error doesn't raised, but %c argument can be silently wrapped (on narrow build) or illegal Unicode string can be created (on wide build). The proposed patch adds explicit range check for %c argument.
