XeTeX UNICODE Table

Question

I would like to try to write a minimal XeTeX source that generates a comprehensive UNICODE table, substituting in local fonts as required by the current plane. I made the attached code as an MWE for people wanting to include small snippets of multilingual text, but want to take it further. This will be my first time attempting loops and conditionals, so any guidance appreciated, particularly on recursively populating tabular environments.

(Please note that this is different than this question in that I do not require automatic font substitution. My goal is to produce a comprehensive reference document from which one could extract precisely the minimum XeTeX code required to include this or that glyph in his or her document.)

===UPDATE===

After reading some of the great answers and comments here, I have the backbone for this project. My immediate, brute force, solution will be to create multido loops for each UNICODE subset currently displaying .notdef glyphs, switching typefaces as required. Definitely open to other, more elegant suggestions.

%!TEX TS-program = xelatex
%!TEX encoding = UTF-8 Unicode

\documentclass[10pt]{article}

% PACKAGES

\usepackage{fontspec}
\usepackage{multicol}
\usepackage{multido}


% FORMATTING

\textwidth = 6.5 in
\textheight = 8 in
\oddsidemargin = 0.0 in
\evensidemargin = 0.0 in
\setlength{\parindent}{0pt}

Answer 1

A simple example using ucharclasses package:

\documentclass{article}
\usepackage{ucharclasses}
\usepackage{fontspec}
\usepackage{bidi}

% some fonts with Windows
\setDefaultTransitions{\fontspec{Times New Roman}}{}
\setTransitionsForCJK{\fontspec{SimSun}}{}
\setTransitionsForArabics{\fontspec{Times New Roman}\setRTL}{\setLTR}
\setTransitionsFor{Gurmukhi}{\fontspec{Raavi}}{}

\begin{document}

\begin{tabular}{ll}
Arabic (MSA) & حَوّامتي مُمْتِلئة بِأَنْقَلَيْسون \\
Chinese (Mandarin, Simplified) & 我的气垫船充满了鳝鱼 \\
Punjabi & ਮੇਰਾ ਹਵਰਕ੍ਰਾਫ਼ਤ ਨਾਂਗਾਂ ਨਾਲ਼ ਭਰਿਆ ਪਿਆ।\\
\end{tabular}

\end{document}

You should read the package document and set the proper fonts.

The use of loop in your question is OK. See also my previous answer in Generating a table of glyphs with XeTeX , but \iffontchar is not necessary.
