Updated HTML Entities Reference using Zenity, Awk, SED.
But right now I'm doing the eBook layout for Steampunk World and I ran into a problem I'd almost forgotten about - extended characters.
Not just your "normal" accented characters, but ones that literally have unicode names of "inodot". So instead of scrolling up and down across four different unicode reference webpages, I updated my referring entities script to be able to search and the reference text file to add extended-A and extended-B.
Basic instructions here:
Because all the tools involved (awk, sed, zenity) are cross-platform, you should be able to make it work pretty easily no matter what system you're on. And the first time you run into a conversion job that has a lot of special characters, you'll thank me.
