Old Korean han'gŭl in XeLaTeX?

Question

Does anybody know if it's possible to typeset old han'gŭl (Korean alphabet) in XeLaTeX?

I'm referring to these letters: http://en.wikipedia.org/wiki/Old_Hangul

It is not possible to type outright on a Mac, but these characters are included in Unicode:

http://en.wikipedia.org/wiki/Hangul_Jamo_(Unicode_block)

I cannot copy and paste the unicode straight into the document, since every syllabic han'gŭl block consists of 2-3 Unicode characters. Usually, the input editor does that assemblage for us, but the Mac input editor doesn't support syllabic blocks containing old han'gŭl.

Minimal working example:

\documentclass[utf8,12pt,letterpaper]{article}

\usepackage{setspace}
\usepackage[fallback]{xeCJK}

\usepackage{fontspec}
\defaultfontfeatures{Ligatures=TeX}

\newcommand{\mainfont}[0]{Times New Roman}\newcommand{\mainfontCJK}[0]{Gulim}
\setmainfont{\mainfont}
\setCJKmainfont{\mainfontCJK}
\XeTeXlinebreaklocale "zh"
\XeTeXlinebreakskip = 0pt plus 1pt

Answer 1

If I didn't misunderstand it, what you need is the “Conjoining Jamo Behavior” described in the Unicode document, or especially the “Hangul Syllable Composition”.

One possible way to do this, is to create a TECkit map file and use it.

1. You may need to write a script program to produce a .map like this (tex-text.map):

   ; TECkit mapping for TeX input conventions <-> Unicode characters
   
   LHSName "TeX-text"
   RHSName "UNICODE"
   
   pass(Unicode)
   
   ; ligatures from Knuth's original CMR fonts
   U+002D U+002D           <>  U+2013  ; -- -> en dash
   U+002D U+002D U+002D    <>  U+2014  ; --- -> em dash
   
   U+0027          <>  U+2019  ; ' -> right single quote
   U+0027 U+0027   <>  U+201D  ; '' -> right double quote
   U+0022           >  U+201D  ; " -> right double quote
   
   U+0060          <>  U+2018  ; ` -> left single quote
   U+0060 U+0060   <>  U+201C  ; `` -> left double quote
   
   U+0021 U+0060   <>  U+00A1  ; !` -> inverted exclam
   U+003F U+0060   <>  U+00BF  ; ?` -> inverted question
   
   ; additions supported in T1 encoding
   U+002C U+002C   <>  U+201E  ; ,, -> DOUBLE LOW-9 QUOTATION MARK
   U+003C U+003C   <>  U+00AB  ; << -> LEFT POINTING GUILLEMET
   U+003E U+003E   <>  U+00BB  ; >> -> RIGHT POINTING GUILLEMET
   

2. Download TECkit and run

   teckit_compile Jamo.map -o Jamo.tec
   

3. Then you can use

   \setCJKmainfont[Mapping=Jamo]{Some Font}

This is only a draft. I am not familar with Korean, so I can't give you a proper final result. Sorry.
