[Cppunit-devel] Toward True Unicode Code... Help requested

[Baptiste L. <gai...@fr...>]

    I intend to give CppUnit true UNICODEsupport in assertion message (the
description of the failure, returned by Exception::what()).

    CppUnit should be able to deal with *both* ANSI and UNICODE string. It's
likely that not every unit tests in a project will use one of those
exclusively.

    The current solution I found to this problem is to introduce a wrapper
string class that can be constructed from either ANSI or UNICODE string
(kind of like the MFC CString). That class would also provides accessor to
retreive the string as either ANSI or UNICODE. Conversion from on format to
another would be done automatically.

    Exception and NotEqualException would be modified to use the string
class described above, as well as Asserter functions (functions that 'do'
the assertion by creating the Exception and throwing it).

    That solution have the advantage of having little impact on the existing
code (both CppUnit and user). Most impact will likely be on Outputter (I
have some really twistest ideas for this, but that for later). Does anybody
see another solution ? Suggestions ?

    On a more technical side, I'm not very familar with Unicode on Windows
(never made an application that truely use Unicode), and just about nothing
on Unix. So here are some questions:

    1) Is std::wstring available on all plateform ?
    2) Are std::wcout, std::wcerr available on all plateform ?
    3) Is the attached code fragment the correct way to do the conversion
between std::string and std::wstring on Windows.
    4) How do we do the conversion on Unix ? Would a dummy conversion (to
and fro iso-latin1) do ?

    Thanks in advance,
    Baptiste.
