I thought this might even be enshrined in an RFC. It certainly makes sense.
If you are using a mailer that sends CP1252 down the wire (not that this is a
good idea, but some mailers do this), the mailer should examine the message
and if it only contains US-ASCII characters, the message should be tagged as
US-ASCII. Otherwise, if it only contains ISO 8859-1, it should be tagged as
ISO 8859-1. Only if it actually contains CP1252 characters, like smart
quotes or long dashes, should it be tagged as CP1252. As Jungshik observed,
the same goes for UTF-8.
