@GuyNoodle: I looked at that solution but too much throwing out the baby with the bath water with that process. The book I was testing on, much like your sample, needed some but not all of the Unicode characters transliterated.
@PeterT: I tried a conversion to kepub and then setting Code2001 as the fallback font. It worked but the contrast between look of the base font and the fallback font was painful to my eyeballs.
