  In this paper we study generic features of nonlocal charges obtained from
marginal deformations of WZNW models. Using free-fields representations of CFTs
based on simply laced Lie algebras, one can use simple arguments to build the
nonlocal charges; but for more general Lie algebras these methods are not
strong enough to be generally used. We propose a brute force calculation where
the nonlocality is associated to a new Lie algebra valued field, and from this
prescription we impose several constraints on the algebra of nonlocal charges.
Possible applications for Yang-Baxter and holographic \(T\bar{T}\) and
\(T\bar{J}\) deformations are also discussed.
