    LÖVR includes Lua 5.3's `utf8` library, even on Lua versions that don't support it.  Lua's
    regular strings aren't utf8-aware, so this library makes it easier to work with multi-byte
    characters that are outside the ASCII range.

    See the [Lua reference manual](https://www.lua.org/manual/5.3/manual.html#6.5) for
    documentation.
