问题
My question is simple. Are all Unicode characters available in Android? I actually am using the soft keyboard and I want to add a few arabic letters which I can't find the codes for.
回答1:
Android supports UTF-8 but you will not be able to use arabic, if it's not installed in your OS. There are ways to install new fonts, but some of them needs jailbreaking your phone.
See link for installing font in Android:

回答2:
It does not appear so. This open issue on the android code site lists many missing characters.
回答3:
add font (.ttf) containing characters to /system/fonts, modify /system/etc/fallback_fonts.xml so android finds font then reboot. Everything should be working now
