# luatex – The LuaTeX engine

LuaTeX is an extended version of pdfTeX using Lua as an embedded scripting language. The LuaTeX projectâ€™s main objective is to provide an open and configurable variant of TeX while at the same time offering downward compatibility.

LuaTeX uses Unicode (as UTF-8) as its default input encoding, and is able to use modern (OpenType) fonts (for both text and mathematics).

It should be noted that LuaTeX is still under development; its specification has been declared stable, but absolute stability may not in practice be assumed.

Source code is available from `ctan:/systems/texlive/source`.
