I am trying to write an image that features characters like z-bar (z with a bar over it to indicate a mean value). I've found the unicode value for a bar glyph, but the only way I can get it to combine with a letter is by plotting the two characters in the same location using multiple calls. Is there a way to combine these into a single string? Or, did I simply miss something like there being a standard glyph that combines these features?
Here's my sample code
And here's he result (the first line was generated using the "noJoy" text layout, the second line by drawing in the same place twice).
