the current implementation of CoreText simply dropped the proper
implementation of DrawTextArray, by ignoring DXArray
this very visibly borked the show-non-displayable character
feature of writer.. the bullet representing the 'spaces'
was quite misplaced.
This solve specifically this problem.
More work is needed to bring proper support of DXArray back to CoreText
