BytesType and UTF8Type

I have some thrift column families that were created with BytesType.  All
the data written to the keys/columns/values were simple string.

In cassandra-cli, I can "correct" these to UTF8Type (I believe both
UTF8Type and BytesType are serialized similarly?) but I can't convert these
blobs to text via CQL.

(1) if my strings are all ascii, is it safe to "correct" the validation
classes?
(2) is the cql restriction merely a safety mechanism that cassandra-cli is
lacking?

Thanks,

Ken

It is, provided your initial assumption ("my strings are all ascii") is
actually true.

It is.
