  A weakly constrained code is a collection of finite-length strings over a
finite alphabet in which certain substrings or patterns occur according to some
prescribed frequencies. Buzaglo and Siegel (ITW 2017) gave a construction of
weakly constrained codes based on row-by-row coding, that achieved the capacity
of the weak constraint. In this paper, we propose a method to make this
row-by-row coding scheme resilient to errors.
