Some recent scientific programming languages like Julia or \(\nabla\) allow the usage of (a subset of) unicode characters [1, 2]. This allows a much more readable code, very close to the mathematical expressions.

Implementation of the Norton behaviour with and without unicode support

This page describes the subset of UTF-8 characters supported in MFront files. This subset includes:
