    Problem Summary PIN4W.00025 This request claims that not supporting input contexts in the C locale is acceptable IUT behavior.
    Problem Text
    We have previously been refused a waiver request for this failure (See PG4W.00094)
    We would like to appeal against this decision and request a 14 day review
    of this refusal.

    The following is an extract from the consultants' review of the original request ...

    "IMs were designed to allow application developers to create
    internationalized applications. An application that uses IMs is
    designed to be used in a variety of locales.

    We believe that an IUT which does not support IMs in the C locale
    is likely to be incapable of running internationalized programs."


    We tend to agree with the consultants' response and the final
    statement seems to be reasonable enough on the surface. However,
    the reality of the situation is that there are many internationalised
    applications which run fine on our platform and the fact that we
    cannot create an IC for the C locale does not appear to have any
    significant impact.

    Assertion XDestroyIC-1.(C)
    If the implementation is X11R5 or later: A call to
    XDestroyIC shall destroy the input context, ic, to the input
    method server.
    METH: There is not a good way to test XDestroyIC. We rely on capturing any
    METH: errors from the server during calls to XDestroyIC. Loop through all
    METH: the input method styles for all the locales, creating and destroying

    shall return the input method, im of the input context, ic
    which was used to create the ic.

    Review Response
    Our opinion remains the same.

    We recommend this request be refused.

    The submitter's statement that Input Contexts (ICs) have little
    use in the C locale is correct. In fact, Input Methods (IMs),
    which require ICs before they may be used, provide no benefit in
    the C locale.

    But this is not the issue here.

    IMs were designed to allow application developers to create
    internationalized applications. An application that uses IMs is
    designed to be used in a variety of locales.

    We believe that an IUT which does not support IMs in the C locale
    is likely to be incapable of running internationalized programs.

    The customer has appealed against the refusal, this is therefore
    being sent for a 14 day anonymous review.

    Review Conclusion
    The current X specifications are silent on this issue. There is no
    requirement for an Input Method to have to support the C locale or even
    for an X application to have to support the C locale. The members do
    not agree with the assertion by the consultant that an "IUT which does
    not support Input Methods in the C locale is likely to be incapable of
    running internationalized programs"

    We therefore recommend that a waiver be granted.
