This is what I have figured out so far: According to the Quartz 2D programming guide "Quartz 2D provides a limited, low-level interface for drawing text encoded in the MacRoman text encoding and for drawing glyphs" which probably explains my problem with using CGContextShowTextAtPoint().
I don't need a layout engine because I only need to put a single glyph at a specific location. I can successfully print a glyph on my view using CGContextShowGlyphs() but as of yet I haven't figured a way to actually find the glyph for the unicode character U+2B06 / E2 AC 86. If I could find a font that has the character I need then I could put it all together. I know the font is available I just don't know how to find it. I'm not sure how to use the string drawing APIs to directly put a unicode UTF8 character onto a specific X,Y location given a CGContextRef.
