I believe (well, I'm quite sure) this is directly related to bug #248708, 'Problem with rendering & selection of "ignorable" characters...', and both of these bugs are at least laterally related to bug/patch #205387, 'need to exclude truly invisible default_ignorable_code_point's from draw_string.' (Thanks to MartijnW for pointing out the connection.) Both of the above are (ostensibly) Win32:GFX bugs, so you may want to recategorise this bug -- just a suggestion, of course.
