Loft/Swipe does not create solid out of curved text!

Hello guys,

I had created those Green and Red texts using flow command, now I want to create a solid out of them I had tried loft and Swipe both of these methods don't give me a solid mesh/object! They just create a shell, how can I fix this problem?

Check the letter "J" to get to know what I mean.

Note: I was able to create solid texts using loft method. However when I bend the created text using flow command the curved text looks mirrored! Also I want the red surfaces inward the curvature not outward!
