Subject: [OASIS Issue Tracker] (ODATA-734) Unicode Facet is inadequate

     [ https://issues.oasis-open.org/browse/ODATA-734?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Pizzo updated ODATA-734:

    Environment: [Proposed]
       Proposal: Services return TRUE if strings support characters outside of the ASCII character set and FALSE if only characters within the ASCII set are supported.  (was: We agreed in 2014-11-13 that the facet is meant to represent the set of characters that the service is able to support for this property.

Further investigation is required to understand whether we can make Unicode==NotAscii or if we need to deprecate the facet and add a capabilities vocabulary term.)

>         Environment: [Proposed]
>            Reporter: Matthew Borges
>            Priority: Minor
>             Fix For: V4.0_ERRATA03
> The Unicode facet appears to be inadequate to handle all possible character sets.  The facet is set to true for unicode character sets and false for ASCII.  The problem is that there exists character sets (such as windows-1252) that is neither unicode nor ASCII.
> In addition, we should also clarify the meaning of the facet in terms of what it applies to.  Does it apply to the character set that is used when the string is on the wire, or the character set in the underlying data store?  My understanding is that it is the character set of the underlying data store, but others may have a different understanding.
