Unable to use 4-bytes unicode when creating volume, volume_type, CG, etc

[Jacob Gregor]

Currently users are unable to use 4-byte unicode characters for operations, such as creating a volume or volume_type. This is because currently our DB's character set is set to utf8, which does not support characters larger than 3 bytes. This is a known issue, as there are other bugs addressing this, as listed below.

However the solutions proposed to these bugs are preventing the user from hitting this issue. A way to allow the users to use 4-byte unicode characters would be to update the DB to use utf8mb4 instead of utf8.

Dear Jacob,

Thanks for raising this, I too agree with this approach.
(But we have to see the pros and cons of same).

To discuss this further with our smart guys and for confirmation of approach, I have kept this topic for discussion in next Cinder meeting.
Please join, lets discuss and fix this.

Sheel,

Thanks for adding this topic to the weekly meeting! I am looking forward to discussing this with everyone.

As discussed in cinder meeting, we should discuss this in cross project as well because this problem would be occurring in all components.
