__STDC_ISO_10646__

[Konrad Schroder]

Is there any particular reason not to implement the requirements for 
__STDC_ISO_10646__, that is, to use Unicode UCS for wchar_t?  Right now 
we use a locale-dependent encoding (and we are not alone in this).

So far as I am aware, using UCS for wchar_t is not required by any 
standard.  But is there any specific reason that we would want to avoid 
using UCS for wchar_t?

Thanks,
