initially intended to be used on musl-based Linux distributions.

@itemize
@item It is portable, works on *BSD, Linux, Solaris and possibly others.
@item It will only trap non-conformant programs.  This means that fortify
  level 2 is treated in the same way as level 1.
@item Avoids making function calls when undefined behaviour has already been
  invoked.  This is handled by using @code{__builtin_trap()}.
@item Support for out-of-bounds read interfaces, such as @code{send()},
  @code{write()}, @code{fwrite()}, etc.
@item No ABI is enforced.  All of the fortify check functions are inlined
  into the resulting binary.

Plan 9's libutf, but with a number of improvements:

@itemize
@item Support for runes beyond the Basic Multilingual Plane.
@item utflen and utfnlen cannot overflow on 32- or 64-bit machines.
@item chartorune treats all invalid codepoints as though Runeerror.
@item fullrune, utfecpy, and utfnlen do not overestimate the length
of malformed runes.
@item An extra function, charntorune(p,s,n), equivalent to
fullrune(s,n) ? chartorune(p,s): 0.
@item Runeerror may be set to an alternative replacement value, such
as -1, to be used instead of U+FFFD.
