Ha, okay. Merci beaucoup daams pour la réponse rapide et précise ! o/

Hi everyone ! I wanted to create a font where characters are squares delimited with lines. But, if i do that, it means that the police would be bicolor (lines would be always black, but square's backgrounds may change color)... I guess it's impossible ? Thanks for your answers !
(Oh, and sorry if i'd done some english mystakes, it's not my native language)
