  .Xr standards 5 for more information about some of these.  Most interfaces
  should support at least UTF-8 in addition to ASCII.
  .It Em INTERFACE STABILITY
  Indicates the level of commitment to the interface. Interfaces can be described
  with in the following ways:
! .Bl -tag
  .It Nm Standard
  Indicates that the interface is defined by one or more standards bodies.
  Generally, changes to the interface will be carefully managed to conform
  to the relevant standards.  These interfaces are generally the most suitable
  for use in portable programs.

  This section describes considerations for the interface when used within
  programs that use multiple threads.  More discussion of these considerations
  is made in the MT-Level section of
  .Xr attributes 5 .
  The interface can be described in the following ways.
! .Bl -tag
  .It Nm Safe
  Indicates the interface is safe for use within multiple threads.  There
  may be additional caveats that apply, in which case those will be
  described.  Note that some interfaces have semantics which may affect
  other threads, but these should be an intrinsic part of the interface
