Describe what characters are valid in service descriptions (ElasticBeanstalk in particular)

[BanzaiMan]

Problem

Some characters are rejected when used in Description in ElasticBeanstalk's UpdateApplicationVersion call, but what characters trip the error is not documented.

It would be great if we can have a list of valid characters for the description.

Background

As reported in travis-ci/dpl#462 and travis-ci/dpl#604, some emoji characters are bad, but http://docs.aws.amazon.com/elasticbeanstalk/latest/api/API_UpdateApplicationVersion.html#API_UpdateApplicationVersion_RequestParameters only has this to say about the Description parameter:

Description
  A new description for this version.

  Type: String

  Length Constraints: Maximum length of 200.

  Required: No

https://github.com/aws/aws-sdk-ruby/blob/ae2f24ce8d444a9579154e187a7e203dbca2cd15/aws-sdk-core/apis/elasticbeanstalk/2010-12-01/api-2.json does not appear to be doing anything special (please correct me if I'm wrong), so I am guessing that the validation happens on the backend, and SDK is simply passing the exception back.

@BanzaiMan Thanks for the information, appreciate that. Correct, SDK doesn't do anything special with that operation, I'll reach out to service team and let them know about this situation : ) At least our service API documentation could do better. Meanwhile, feel free to open a ticket to AWS Support to get direct attention as well.

This has been added to service team doc backlog and they are working on it, closing.
Yet feel free to reopen with further comments or requests : )
Thanks again for bringing this up.

[BanzaiMan]

From this, I take it to mean that the documentation would be updated to show the valid characters in version description in the near future.

Thank you very much for the quick turnaround!

[cjyclaire]

@BanzaiMan Exactly : )

@cjyclaire Hello. It's a bit over a month now, but the documentation has not been updated. Perhaps I'm a little impatient, but I'd appreciate some updates. Thank you!

[cjyclaire]

@BanzaiMan No worries, I'll follow up with service team with this : ) appreciate your patience!

[BanzaiMan]

@cjyclaire The documentation is still unclear. Could you check the documentation back log, if you can? Thank you!

[cjyclaire]

@BanzaiMan Apologies, I have pinged them again :( will update

Hello there. I am sorry to ping again, but the documentation remains unclear. :-(
