If "printable" is defined as "printable ASCII", that's likely not to falsely
claim a binary OctetString is text - but it won't treat any non-ASCII string as
printable, even if it is, for example, UTF-8.

If "printable" is defined as "printable Unicode, UTF-8 encoded", will it be too
likely to falsely claim a binary OctetString is text?

Would this be better done by having the .cnf file for the protocol indicate
which OctetStrings are intended to be printable (or, perhaps, "possibly
printable"), and either should always be strings or should be "strings if
they're valid printable UTF-8", and which are definitely binary and should
never be strings?
