I should know what font to use, that is available in all operating systems. And how to properly scale and position the character.(should check how the size and position of the character depends on the size of the font)

Manually tried to align them: http://old.etoleto.com/c1/ (orange circles are of text, transparent blue ones of divs) I'm not sure if i should use this instead of divs - being able to select them as text annoys
