Comment 0 for bug 1061150

The python-glanceclient chokes on unicode for image names, metadata keys, and metadata values.

Examples:
# unicode in name
$ MERC=$(echo -e "\u263f")
$ echo $MERC
☿
$ glance image-create --name Freddy-$MERC
'ascii' codec can't decode byte 0xe2 in position 30: ordinal not in range(128)

$ BB=$(echo -e "\u2047")
$ CC=$(echo -e "\u2048")
$ echo $BB
⁇
$ echo $CC
⁈

# unicode in metadata value
$ glance image-update --property ascii_key=unicode-${BB} 7a40d9d3-ee1d-48a1-8e2a-6c8ae01b7b4c
'ascii' codec can't decode byte 0xe2 in position 45: ordinal not in range(128)

# unicode in metadata key
$ glance image-update --property unicode_key_${CC}=ascii-value 7a40d9d3-ee1d-48a1-8e2a-6c8ae01b7b4c
'ascii' codec can't decode byte 0xe2 in position 38: ordinal not in range(128)

NOTE: The glance API can handle unicode fine:
$ VAL=$(echo -e "\u2645")
$ KEY=$(echo -e "\u262e")
$ echo $VAL
♅
$ echo $KEY
