j2d - translating Java to D with the language machine - progress

[Peri Hankey]

It looks now as if the 'invalid UTF character' message is a problem with 
the gdc/dmd front end in the version (gdc 0.17/dmd140) that I am using. 
Is this fixed in later versions of dmd? How else would a java string

    '\uffff'

be translated as initialising a D language wchar variable? The following

    wchar x = '\uffff';

is flagged as invalid.
