Undeciphered writing systems

Undeciphered writing systems are proposed writing systems for which no decipherment has achieved broad acceptance in the specialist literature. While most examples are ancient, a small number are medieval or modern. In some cases the evidence is too limited to determine whether the marks represent a true writing system, a form of proto-writing, or a set of non-linguistic symbols; modern artistic traditions such as asemic writing likewise imitate the appearance of writing while intentionally withholding stable linguistic meaning.
