/**
* @file wtt.h
* @brief WTT I/O implementation
*
* 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.
*
* WTT classifies Thai chracter(TIS-620) into 17 types below.
*
* <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>
*
* Functions in thctype.h do basic character classifications while
* wtt.h classifies a chracter in detail. Please refer to the reference.
*
* TACio_op() 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 wtt.h.
* And their meanings are:
*
* @li CP : second character is displayed in the same cell as the first,
* also implies an acceptance.
* @li XC : Do nothing.
* @li AC : Display second character in the next cell.
* @li RJ : Discard second character.
* @li SR : Reject second character only in strict mode.
*
