<div class="textblock"><p>WTT I/O implementation. </p>
<p>WTT stands for Wing Tuk Tee (in Thai, Runs everywhere). It was defined by TACTIS (Thai API Consortium/Thai Industrial Standard) in the NECTEC Thai Software Standard Project (1989-1991), and later endorsed by Thai Industrial Standard Institute (TISI) as TIS 1566-2541 in 1998.</p>
<p>WTT classifies Thai chracter(TIS-620) into 17 types below.</p>
<pre>
<b>ITYPE VALUE SHORT_DESCRIPTION</b>
CTRL 0 control characters
NON 1 non composible characters
CONS 2 consonants
LV 3 leading vowels
FV1 4 following vowels 1
FV2 5 following vowels 2
FV3 6 following vowels 3
BV1 7 below vowels 1
BV2 8 below vowels 2
BD 9 below diacritics
TONE 10 tonemarks
AD1 11 above diacritics 1
AD2 12 above diacritics 2
AD3 13 above diacritics 3
AV1 14 above vowels 1
AV2 15 above vowels 2
AV3 16 above vowels 3
</pre><p>Functions in <a class="el" href="thctype_8h.html" title="Thai character classifications.">thctype.h</a> do basic character classifications while <a class="el" href="wtt_8h.html" title="WTT I/O implementation.">wtt.h</a> classifies a chracter in detail. Please refer to the reference.</p>
<p><a class="el" href="wtt_8h.html#ab8ea276ab09ecde7c01b48c6251abaa5" title="WTT I/O operation.">TACio_op()</a> checks how to compose two given chracters. The possiblities are Composible (CP), Non-display (XC), Accept (AC), Reject (RJ) and Strict Reject (SR). The values of CP, XC, AC, RJ and SR are difined in <a class="el" href="wtt_8h.html" title="WTT I/O implementation.">wtt.h</a>. And their meanings are:</p>
<ul>
<li>CP : second character is displayed in the same cell as the first, also implies an acceptance. </li>
<li>XC : Do nothing. </li>
<li>AC : Display second character in the next cell. </li>
<li>RJ : Discard second character. </li>
<li>SR : Reject second character only in strict mode. </li>
