Chicago Template Bib(La)Tex [Biber] convert to XeLaTeX for Hebrew support

%runs in texmaker with Quickbuild =
pdflex->biblatex->pdflatex(x2)->view pdf
%that makes all the citekeys hook up to the .bib file and makes ibid
work and all that stuff

Adding little bit of hebrew breaks everything, simple fixes like changing usepackage[utf8]{inputenc} to utf8x doesn’t work, that one breaks biber

can you rewrite this to use polyglossia and xelatex instead of babel?

MWE:

%filename: main.tex
documentclass[a4paper,hebrew,english]{article}
usepackage[T1]{fontenc}
usepackage[utf8]{inputenc}
usepackage{lmodern}
%usepackage{cjhebrew}
usepackage[hebrew,english]{babel}
usepackage{csquotes}

usepackage[notes,backend=biber]{biblatex-chicago}
bibliography{sample}

that file main.tex pulls from this one sample.bib to auto-complete the citekeys {Ful83} and {GMP81} and replace them with Author names and book titles. How can I type Hebrew into the main body or into the footnotes without breaking this nice Chicago template that actually works?

%filename = sample.bib
@conference{Ful83,
   author = "William Fulton",
    title = "Introduction to intersection theory in algebraic geometry",
booktitle = "Regional Conference Series in Mathematics",
   number = 54,
     year = 1983}

@inproceedings{GMP81,
   author = "Mark Goresky and Robert MacPherson",
    title = "On the topology of complex algebraic maps",
booktitle = "Algebraic Geometry Proceedings, La R'abida,
             Lecture Notes in Mathematics",
   number = 961,
     year = 1981}
