+\title{The \texttt{C90} encoding for Thai}
+\author{Werner Lemberg}
+\date{2005/07/04}
+\maketitle
+
+
+\section{Introduction}
+
+This file describes a font encoding for Thai, as presented in a
+TUGboat article~\cite{TUG-Thai}. The glyph names follow the Adobe
+Glyph List (AGL)~\cite{AGL} recommendations. Since most available
+Thai fonts neither use AGL glyph names nor follow the font encoding
+used here, you have to be careful in setting up a proper encoding
+vector. A specialty (for reasons explained below) is that three
+glyphs, namely |/uni0E38| (Thai character `sara u'), |/uni0E39| (Thai
+character `sara uu'), and |/uni0E3A| (Thai character `phinthu') must
+appear twice in the encoding; the additional glyph indices are |0x80|,
+|0x81|, and |0x82|, respectively.
+
+
+\section{Ligatures}
+The tricky part is implementing the ligatures. TeX's ligature
+mechanism only provides contextual patterns of length~2. Due to the
+very nature of the ETX format, ligatures aren't grouped into classes
+which makes this file rather long.
+
+Thai glyphs can be grouped functionally into base glyphs (which are
+spacing glyphs) and diacritics (which have zero advance width).
+Usually, diacritical glyphs represent either vowels or tone
+indicators, whereas base glyphs represent consonants -- I won't go
+into detail here; please read the Unicode standard~\cite{Unicode} or
+any introduction into the Thai script for more information.
+
+The general composing rules are as follows:
+
+\[
+ CV \longrightarrow \StackAbove{V}{C}\,,\quad
+ CT \longrightarrow \StackAbove{T}{C}\,,\quad
+ CVT \longrightarrow \StackAbove{\StackAbove{T}{V}}{C}\,,\quad
+ Cv \longrightarrow \StackBelow{C}{v}\,,\quad
+ CvT \longrightarrow \StackBelow{\StackAbove{T}{C}}{v}
+\]
+
+\noindent
+where $C$ represents a base consonant, $V$ an upper vowel, $v$ a lower
+vowel, and $T$ a tone mark. The tone mark always comes last.
+
+Sometimes you will find documents which have first the tone mark and
+then the vowel. In real Thai input systems, this error will be
+catched and fixed by reordering the characters according to the
+TIS-620 Thai encoding standard before any output is created. The
+ligatures given below are not able to handle such incorrect data, and
+you have to normalize it before using them.
+
+It depends on context where the diacritics are exactly positioned;
+some base glyphs have overlong ascenders or descenders, making it
+necessary to shift the diacritics vertically and horizontally.
+
+To complicate things, the Thai vowel `sara am' (TIS-620 code point
+|0xD3|, Unicode value |U+0E33|), which looks like the final nasal sign
+`nikhahit' (|0xED|, |U+0E4D|) followed by the vowel `sara aa' (|0xD2|,
+|U+0E32|), will be decomposed into these two glyphs for rendering.
+The difficulty is that we must position the tone mark of the
+\emph{previous} character properly! Thus we have
+
+\[
+ C + SM \longrightarrow \StackAbove{N}{C} + SA\,,\quad
+ C + T + SM \longrightarrow \StackAbove{\StackAbove{T}{N}}{C} + SA
+\]
+
+A last specialty (used for Sanskrit written in Thai) is that `sara aa'
+if it follows the independent vowel letter `ru' (|0xC4|, |U+0E24|) or
+`lu' (|0xC6|, |U+0E26|) is replaced with the `lakkhangyao' sign
+(|0xE5|, |U+0E45|).
+
+
+\section{Glyph Classes}
+
+To describe the patterns and rules we start with defining glyph
+classes.
+
+\begin{quote}
+ \begin{description}
+ \item[\thaiclassx{base}{normal}] Normal base glyphs without special
+ features.
+ \item[\thaiclassx{base}{desc}] Base glyphs with descender.
+ \item[\thaiclassx{base}{desclike}] These base glyphs consist of two
+ elements which look like a normal base glyph combined with a lower
+ vowel diacritic; the diacritic-like element will be omitted if
+ combined with a lower vowel.
+ \item[\thaiclassx{base}{asc}] Base glyphs with an ascender on the
+ right side.
+ \item[\thaiclassx{base}{indic}] The two independent vowels \emph{ru}
+ and \emph{lu}.
+ \item[\thaiclassx{base}{sign}] The sign \emph{lakkhangyao}.
+ \item[\thaiclassx{base}{sara am}] The vowel \emph{sara am}.
+ \item[\thaiclassx{base}{sara aa}] The vowel \emph{sara aa}.
+ \item[\thaiclass{lower}] Lower vowel diacritics.
+ \item[\thaiclassx{upper}{vowel}] Upper vowel diacritics.
+ \item[\thaiclassx{upper}{sign}] The \emph{nikhahit} final nasal
+ sign.
+ \item[\thaiclass{top}] Tone marks.
+ \end{description}
+\end{quote}
+
+Here the glyph variant classes:
+
+\begin{quote}
+ \begin{description}
+ \item[\thaiclassx{base}{descless}] The glyphs of class
+ \thaiclassx{base}{desclike} without the lower part.
+ \item[\thaiclassx{lower}{low}] The glyphs of class
+ \thaiclass{lower} shifted downwards.
+ \item[\thaiclassxx{upper}{vowel}{left}] The glyphs of class
+ \thaiclassx{upper}{vowel} shifted to the left.
+ \item[\thaiclassxx{upper}{sign}{left}] The glyphs of class
+ \thaiclassx{upper}{sign} shifted to the left.
+ \item[\thaiclassx{top}{left}] The glyphs of class
+ \thaiclass{top} shifted to the left.
+ \item[\thaiclassx{top}{low}] The glyphs of class
+ \thaiclass{top} shifted downwards.
+ \item[\thaiclassx{top}{low-left}] The glyphs of class
+ \thaiclass{top} shifted to the left and downwards.
+ \end{description}
+\end{quote}
+
+
+\section{Context Patterns}
+
+Using the glyph classes defined in the last section it is easy to
+describe the context patterns for base glyphs with diacritical signs.
+Surprisingly, these patterns are quite systematic. Patterns in
+table~\ref{table:context-dia} which are marked with an asterisk do
+nothing and are listed for completeness only. Note that these
+patterns cover combinations which don't happen in the Thai script
+(which doesn't harm).

+\section{\TeX's Ligature Mechanism}
+
+\DeleteShortVerb{\|}
+
+A small introduction into the exotic variants of \TeX's ligature
+mechanism which probably many users haven't seen before.
+Additionally, the documentation in the \emph{\MF book}~\cite{MFbook}
+is very sparse. In the following examples \MF's notation is used.
+
+The usual ligature action of two glyphs $a$ and~$b$ is the replacement
+of both glyphs with another glyph~$c$.
+
+\begin{center}
+ \texttt{a b =:\ c}
+\end{center}
+
+Another possibility is to retain the left or the right original glyph
+(before and after the ligature, respectively) or both.
+
+\begin{center}
+ \texttt{a b |=:\ c} \quad
+ \texttt{a b =:| c} \quad
+ \texttt{a b |=:| c}
+\end{center}
+
+\noindent
+The first rule creates $ac$, the second $cb$, and the last $acb$. In
+all three cases, the current point after appying the ligature rule is
+still at the first glyph of the replaced glyphs, and \TeX\ simply
+restarts there to check ligatures (and kernings). A classical example
+is
+
+\begin{center}
+ f f i \textrightarrow\ ff i \textrightarrow\ ffi
+\end{center}
+
+To advance the current point to the right, append either \texttt{>} or
+\texttt{>{}>} (the latter is only possible if you retain both input
+glyphs). Here are the remaining four ligature rules.
+
+\begin{center}
+ \texttt{a b |=:> c} \quad
+ \texttt{a b =:|> c} \\
+ \texttt{a b |=:|> c} \quad
+ \texttt{a b |=:|>{}> c}
+\end{center}
+
+For Thai ligatures, the most often needed rule is \texttt{|=:}\ (i.e.,
+retain the left glyph and stay at the same position before applying
+the next ligature rule). Note that using \texttt{|=:>} instead is not
+a good idea since this would prohibit kerning between the left glyph
+and the ligature.
+
+\section{Ligature Rules}
+
+\MakeShortVerb{\|}
+
+As just explained, \TeX\ can only handle context patterns of length~2,
+whereas Thai needs patterns of length~3. It was an interesting
+challenge to find out whether the problem can be solved with \TeX's
+somewhat restricted ligature rules -- the gentle reader is invited to
+find a solution by herself! There won't be any difficulties in
+understanding ligatures afterwards.
+
+The tables~\ref{table:liga-dia}, \ref{table:liga-sara},
+and~\ref{table:liga-indic} use the same conventions as
+tables~\ref{table:context-dia}, \ref{table:context-sara},
+and~\ref{table:context-indic}, respectively. The current point isn't
+increased in any of the rules.

+ \end{tabular}
+ \caption{Ligature rule for \emph{ru} and \emph{lu}.}
+ \label{table:liga-indic}
+\end{table*}
+
+Most of the ligature rules can be derived easily by handling the
+patterns sequentially (quite similar to logic puzzles found in various
+magazines), but at the end there remain two patterns which apparently
+contradict.
+
+\setlength{\tabcolsep}{3pt}

+\begin{center}

+ &\thaiclassx{base}{asc} &\thaiclass{lower}
+ &\thaiclassx{top}{low-left} \\
+ \end{tabular}
+\end{center}
+
+After applying ligature rules for the first two glyph classes it is
+necessary to handle the context `\thaiclass{lower} \thaiclass{top}',
+but depending on the previous glyph class \thaiclass{top} must be
+replaced with \thaiclassx{top}{left} and \thaiclassx{top}{low-left},
+respectively. With a context pattern length of~3 this would be easy
+to solve, but \TeX\ doesn't have this feature. What to do?
+
+The context `\thaiclass{base} \thaiclass{lower} \thaiclass{top}' must
+be distinguished from `\thaiclassx{base}{asc} \thaiclass{lower}
+\thaiclass{top}', i.e., two different \thaiclass{lower} classes are
+needed depending on the previous character since \TeX\ is not able to
+forward information from one ligature cycle to the next. The idea is
+now to create an `alias class', a class which behaves identically to
+the original one. The glyphs in this alias class are the same, but
+different glyph indices and glyph names are assigned to it. A
+closer look to table~\ref{table:liga-dia} shows that
+\thaiclassx{lower}{left} isn't a typo but the alias class of
+\thaiclass{lower}.
+
+
+\section{The Implementation}
+
+After solving the problem theoretically now the practical
+implementation. All glyph names follow the \emph{Adobe Glyph List
+ (AGL)}~\cite{AGL}. There are no predefined Adobe glyph names for
+Thai, so the prefix `uni' with attached Unicode value will be used for
+all glyphs which are encoded in Unicode. Glyph variants are
+identified by an arbitrarily chosen postfix.
+
+Here the real glyph names for the various classes. Hexadecimal values
+in parentheses after the glyph name give the glyph indices in the
+encoding vector.

+\section{Non-Thai Characters}
+
+Of the many different \LaTeX{} encodings, |OT1| supports {\small
+ ASCII} best (and this is what most Type~1 Thai fonts have). This
+has two advantages: We can use the raw Thai font without specifying a
+new encoding (switching to |OT1| will be sufficient), and it will work
+with plain \TeX{} also.
+
+We use the |OT1| layout for typewriter fonts (i.e., for |cmtt|) with
+the exception that `arrowup' and `arrowdown' are replaced with
+`endash' and `emdash', and the seldom used `dotlessj' with
+`quotedblleft'.

+
+This is |TIS-620| encoding with glyph variants. The encoding presented
+in~\cite{TUG-Thai} contained two alternate glyph forms at positions 157
+and 158 which have been removed meanwhile.
+
+The number of all Thai ligature rules is quite big (464~in total).
+Note that |vptovf| will make the ligature table much more compact as
+it may appear here.
