In The Unicode Standard, Syriac Script implementation is discussed in  Chapter 9 Middle East-I: Modern and Liturgical Scripts. The Unicode Syriac block combines all three main script variants (Estrangelo, Eastern and Western) in a single set of character codes.

Syriac script was first encoded in The Unicode Standard version 3.0. The script is encoded in the following block:
