/**
 * <p>
 * An imperfect, incomplete reverse mapping of ASCII characters to
 * case-insensitive regexes that match their most common accented forms.
 * </p>
 *
 * <p>
 * The goal of this module is to provide a pragmatic and generally useful set of
 * accent folding data, since serving and performing lookups on a complete
 * dataset would be impractical in client-side JavaScript.
 * </p>
 *
 * <p>
 * Whenever possible, accent folding should be done on the server, where it's
 * possible to use tools that are both more complete and more performant. It
 * should only be done on the client as an absolute last resort.
 * </p>
