New submission from Yury Selivanov:
Right now, Python 3.6b4 happily accepts the following:
>>> f'{10:02\N{LATIN CAPITAL LETTER X}}'
'0A'
>>> f'{10:02X}'
'0A'
I think that the first line should not be accepted (as we now don't accept
escaped open curly brace).
At least this should be documented in the PEP as a thing that shouldn't be
relied upon, i.e. something that might not be supported in the future versions.
