Is There A Font Editor That Handles 9 Column Fonts?

jared spiegel asks: "After playing with SVGATextMode for a while, I've noticed that using any font as '9x?' interferes with lots of ASCII art (especially with certain 8-bit ASCII characters) since it seems to tack an extra column of white space on the right-most end of each character. I'm guessing this is because of the 8 column font being expanded to 9 columns. I can't find an editor that is capable of creating/editing 9 column fonts, however. CFE and Fonter are the only ones i've found, yet both of these are hard-coded for 8 column fonts. Does such an editor exist?"
