In any criminal case in which it appears to the satisfaction of the trial judge that a witness who has been required to enter into an undertaking, with sureties, for the witness’s appearance at the trial court, was committed to and confined in prison because the witness actually was unable to obtain and furnish acceptable sureties by reason of being a stranger or a transient in the community, or for other good and sufficient reason, such judge may order the allowance to such witness, and the payment by the proper county, of witness fees, at the rate of fifty cents per day, for and during the period of imprisonment.
