ANGKHANKHU + * 0xFB <U0E5B> THAI CHARACTER KHOMUT + * </pre> + * + * Thai characters consist of 44 consonants, vowels, tonemarks, diacritics and + * Thai digits. Thai vowels are divided into 4 groups, Leading Vowels (LV), + * Following Vowels (FV), Below Vowels (BV) and Above Vowels (AV). There are 4 + * tonemarks whose position is above a consonant. Diacritics are divided into + * 2 groups, Above Diacritics (AD) and Below Diacritics (BD). + * + * Libthai has defined 4 levels for the position of a character. + * + * @li Below level: a character is placed below the consonant. + * th_chlevel() will return the value -1 for these characters. + * + * @li Base level: this includes consonants, FV and LV. A character is + * placed on baseline. + * th_chlevel() will return the value 0 for these characters. + * + * @li Above level: a character is placed just above the consonant. + * th_chlevel() will return the value 1 for these characters. + * + * @li Top level: this includes tone marks and diacritics. For plain + * character cell rendering, it is safe to put these characters at + * top-most level. However, some rendering engines may lower them down + * on absence of character at Above level, for typographical quality. + * th_chlevel() will return the value 2 for these characters. + * + * There is an extra level value 3 for certain characters which are usually + * classified as characters at Above level, but are also allowed to be placed + * at Top level for some rare cases. Two characters fall in this category, + * namely MAITAIKHU and NIKHAHIT. + * + * MAITAIKHU can be placed at Top level when writing some minority languages + * such as Kuy, to shorten some syllables with compound vowels, such as Sara + * Ia and Sara Uea. NIKHAHIT can be placed at Top level in Pali/Sanskrit words, + * to represent -ng final sound above SARA I. + * + * The following figure illustrates a Thai word and characters' level. + * + * <pre> + * --------------------------- Top(2) + * ------*-------------------- Top(2) + * ------*-------------------- Top(2) + * <b>---------------------------</b> + * --------------------------- Above(1) + * ------*---------------*---- Above(1) + * ---****---------------*---- Above(1) + * --------------------------- Above(1) + * <b>---------------------------</b> + * --------------------------- Base(0) + * --*---*----***-----*--*---- Base(0) + * -*-*-*-*--*---*---*-*-*---- Base(0) + * --**-*-*------*---**--*---- Base(0) + * ---**--*---*--*---*---*---- Base(0) + * ---**--*--*-*-*----*--*---- Base(0) + * ---*---*--**--*---*---*---- Base(0) + * ---*---*--*---*---*---*---- Base(0) + * ---*---*--*****---*****---- Base(0) + * <b>--------------------------- Baseline</b> + * --------------------------- Below(-1) + * -------------------**-*---- Below(-1) + * --------------------***---- Below(-1) + * --------------------------- Below(-1) + * </pre> + * + * A character placed at below, above or top level is also called dead + * character.
