Android UTF-8 edittext not displayed

I want to display some UTF-8 characters (upside down) in my edittext:

ʇxǝʇ ǝɯos

This works for the all characters, except the e . The e can't be displayed in the edittext. Is there a reason why it can't be displayed?

the "e" is of type LATIN_EXTENDED_B, can't android display those characters ?

Thanks!
