This will be encoded in the solution content. In other words, database
doesn't need
to know how exactly solution is presented/how input is accepted/how it
is processed.

Alternatively we could allow teacher to "reject" the solution - that is
it will not result in
any change to overall score of student. The rejection will have a reason
attached to it, and one
of the options will be "Unsupported language used". We can add list of
acceptable languages,
but
a. it should be attached to teacher, since he is the one checking
results (may be different person
then problem author, or translator)
b. It can only be advisory anyways - nothing prevents me, as a student,
marking solution as
written in English, while actually writing it in Russian, or translit.
