Convert single unicode character to png image I need to convert a Unicode character (e.g. ⦿; CIRCLED BULLET; U+29BF) to a PNG image for use within a reporting tool (Crystal Reports).  I need to preserve the font, size, and formatting of the character.

Is there a more-accurate way to do this than just ⌘⇧+4 and a less-burdensome way than Gimp or Seashore?
Using ImageMagick:

convert -pointsize 64 -font /System/Library/Fonts/Apple\ Symbols.ttf label:⦿ output.png

convert -background transparent -fill 'hsb(0%,0%,0%)' -font /System/Library/Fonts/Apple\ Symbols.ttf -pointsize 64 -size 200x200 -gravity center label:⦿ output.png
