nova boot failed when use the chinese metadata key and value

[shuangyang.qian]

I get the wrong msg like bellow:

Invalid input for field/attribute metadata. Value: {u'\\u4e2d\\u6587\\u5143\\u6570\\u636e': u'\u963f\u65af\u987f\u53d1\u751f'}. Additional properties are not allowed (u'\\u4e2d\\u6587\\u5143\\u6570\\u636e' was unexpected) (HTTP 400) (Request-ID: req-3e9ea1d0-8384-41e9-8b00-36e6740262e4)

I think it't better to support the chinese key.

anyone who notice this bug or defect? may be i describe this problem not very clearly.

when boot VM with Chinese metadata, it failed with the error that invalid input. I think we should fix this to support Chinese metadata key.

Hello. A few of us discussed this in IRC today [1]. Can you please provide more specifics about what's driving this? Is it a need or a want? What specific use case(s) are you trying to address?

Thanks!

Hello ,I'm very sorry,i didn't take part in it in time discussed in IRC.I want to solve metadata key support chinese.

[Eric Fried (efried)]

Right, we understand *what* you're trying to do. We'd like to know *why*.

[Eric Fried (efried)]

Still need to understand the motivation for this.

@Eric Fried
Some customers in China need to set metadata's key in Chinese. So that they can do some customized operations using Chinese.
For flavor extra specs, there's no need to support unicode for key so far.

More core team discussion [1] concluded that, if we're going to do this, it's going to need a blueprint/spec and most likely a microversion. If you wish to pursue it, you may register a blueprint here [2] and submit a spec to the nova-specs repository. More information on this process can be found at [3].

Thanks!
