Get UTF-16 characters into PDF Document

I am trying to figure out how to get unicode characters that don't begin with \u00 to render as PDF.

The following PDF works fine, because the Unicode character i'm tryng to render starts with \u00

The following PDF DOES NOT work, it gives me a question mark, because the Unicode character i'm tryng to render DOES NOT START WITH \u00
