Charset-based or language-based filtering seems more reasonable option to me
(although automatic language recognition requires some computational power).
As with every heuristic, YMMV.
* Schools may have foreign-language classes and partnerships with schools in
corresponding countries.
* Regular users of your mail service may enjoy communicating in foreign
languages, either because they are learning
them (I know people who learn chinese for fun) or because it's their native
language when they're immigrants. Unless
you know every user of your mail service and can be reasonably sure that
they all use a single language, rejecting
based on language/charset may hit legitimate mail.
Of course, every filtering strategy can be considered "wrong" or "unreasonable" as soon as it creates false positives. I
have yet to encounter a filtering strategy (with the possible exemption of the "null-filter") that is guaranteed to
create no false positives. You need a working process for dealing with false positives.
