thai/wtt.h -
WTT I/O implementation.
SYNOPSIS
Enumerations
enum WTTClass { CTRL = 0, NON = 1, CONS = 2, LV = 3, FV1 = 4, FV2 = 5, FV3 = 6, BV1 = 7, BV2 = 8, BD = 9, TONE = 10, AD1 = 11, AD2 = 12,
AD3 = 13, AV1 = 14, AV2 = 15, AV3 = 16 }
Classification of characters in TIS620 according to WTT.
enum WTTOp { CP = 1, XC = 2, AC = 3, RJ = 4, SR = 5 }
Composibility checking tables.
Functions
WTTClass TACchtype (thchar_t c)
WTT character class.
WTTOp TACio_op (thchar_t c1, thchar_t c2)
WTT I/O operation.
Detailed Description
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.
ITYPE VALUE SHORT_DESCRIPTION
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
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:
o CP : second character is displayed in the same cell as the first, also implies an acceptance.
o XC : Do nothing.
o AC : Display second character in the next cell.
o RJ : Discard second character.
o SR : Reject second character only in strict mode.
