Hi,

This series failed the docker-quick@centos7 build test. Please find the testing 
commands and
their output below. If you have Docker installed, you can probably reproduce it
locally.

make docker-image-centos7 V=1 NETWORK=1

Interesting:

[root@kvm up-coroutine-wrapper]# grep --color='auto' -P -n '[^\x00-\x7F]' 
include/block/block.h
307:     * Child from which to read all data that isn’t allocated in the
                                                     ^

The file really contains one non-ascii symbol. I think it worth a separate 
patch. Still, it shouldn't break build process. On my system it works as is, 
probably unicode is default for me.

Aha, from "open" specification:

   if encoding is not specified the encoding used is platform dependent: 
locale.getpreferredencoding(False) is called to get the current locale encoding.



Is it ok, that utf-8 is not default on test system?

So, possible solutions are:

1. Enforce utf-8 io in scripts/block-coroutine-wrapper.py (patch 4)
2. Drop non-ascii quotation mark from block.h
3. Fix the test system default to be utf-8

Do we want them all?
