First, as a point of reference, here are a few positive-width Unicode
characters:
0020: _ _ | 00E9: _é_ | 03A9: _Ω_ | 5B57: _字_ | 1F407: __
All fine for me!(GMail seems to strip emoji in plain-text replies though.. which is rather odd.)
FFF9: __
FFFA: __
FFFB: __
These three show as the replacement box for me.I've never quite understood what the "inter annotation" whatevercharacters are - but I think they're some form of control character sohaving them display as a box when used incorrectly might be correct.
E0020: __
... (E0020–E007F used for invisibly tagging texts by language)
E007F: __
These *were* used for tagging texts by language, but have beendeprecated in favour of using other non-Unicode metadata for thispurpose.They are planned to be used in emojis and are (were?) used (but notwidely supported) for country codes/flags with codes longer than 2characters (3?), such as USA states or counties of England.Wikipedia has a ~ok description of their history.=
