Issues with uncommon UTF characters Android

[SnoopRekt]

Hi everyone,

I'm a huge language nerd and I rely heavily on my Android device to learn (An Xperia M4 Aqua on Lollipop). I recently took a jab at Ainu, an old native language from Northern Japan. Because of the way the language works, it uses a variety of characters from the Japanese Katakana script in smaller variants (Symbol codes here: http://sites.psu.edu/symbolcodes/languages/asia/ainu/). Probably because Android's a lighter OS, these characters don't appear. I was wondering if there's any method to patch them in. Any help is appreciated!

Edit: I'm also having issues with traditional Mongolian script and Tibetan now
