In this work we exhibit examples of 5-manifolds that are not homeomorphic to any leaf of any C² codimension one foliation of any compact 6-manifold but are homeomorphic to (proper) leaves of some C¹ codimension one foliations and also to (proper) leaves of some C^ codimension 2 foliations. The topology of these manifolds is characterized by Sturmian-like sequences.
