Display a specific Unicode character on different Android version -

i'm trying display specific unicode character("\u24ba",Ⓔ) receive api , try display in textview.

the display work on android 5+. however, when try on android 4.2 , 4.4 got different behavior.

android 4.2 replace character empty string. android 4.4 replace character uppercase e.

my initial though android 4+ font doesn't handle unicode character , decided implement typeface roboto_medium.ttf

typeface medium = typeface.createfromasset(context.getassets(), "roboto-medium.ttf"); name.settypeface(medium); name.settext("Ⓔ");  or name.settext(html.fromhtml("\u24ba"); 

i got exact same result describe above.

any idea ?
