// TODO: perhaps have a "bare" version of the index (used by this package) that
// is not pre-loaded with all encodings. Global variables in encodings prevent
// the linker from being able to purge unneeded tables. This means that
// referencing all encodings, as this package does for the default index, links
// in all encodings unconditionally.
//
// This issue can be solved by either solving the linking issue (see
// https://github.com/golang/go/issues/6330) or refactoring the encoding tables
// (e.g. moving the tables to internal packages that do not use global
// variables).

// TODO: allow canonicalizing names
