RFC 2046 p. 4.1.2.  Charset Parameter
  ___
/
    In general, composition software should always use the "lowest common
    denominator" character set possible.  For example, if a body contains
    only US-ASCII characters, it SHOULD be marked as being in the US-
    ASCII character set, not ISO-8859-1, which, like all the ISO-8859
    family of character sets, is a superset of US-ASCII.  More generally,
    if a widely-used character set is a subset of another character set,
    and a body contains only characters in the widely-used subset, it
    should be labelled as being in that subset.  This will increase the
    chances that the recipient will be able to view the resulting entity
    correctly.

Zwracam uwagę na użycie „should” – czyli nie jest to nakaz, a zalecenie.
