Late to this, but I'd be amazed if Emacs doesn't already have functionality equivalent to this in the standard library. :-)

BTW, the recipe could have been defined slightly more simply with :files (:defaults "data").

Thanks for pushing the simplification!

I asked on help-gnu-emacs yesterday whether Emacs has equivalent functionality built-in and Eli Zaretskii responded. He says that ucs-normalize.el can be used to remove accents, and some scripts have input methods that support transliteration, but nothing as general as Unidecode.

@johnmastro Good to know. This certainly looks useful - thanks for sharing.
