I do sharpen it in Gimp but the jpg created by UFRAW is softer than the original. The original sharpness cannot be retrieved again. I can give you a comparison of another program if you like.
I can zoom into the eyes in UFRAW and they are completely in-focus and sharp but the created jpg's eyes are much softer.
