William, fyi, definitions can be found in the Unicode glossary http://www.unicode.org/glossary (They are helpful and easy to access although I often find them weak or wanting.)
digraph http://www.unicode.org/glossary/#digraph Digraph. A pair of signs or symbols (two graphs), which together represent a single sound or a single linguistic unit. The English writing system employs many digraphs (for example, th, ch, sh, qu, and so on). The same two symbols may not always be interpreted as a digraph (for example, cathode versus cathouse). When three signs are so combined, they are called a trigraph. More than three are usually called an n-graph. ligature http://www.unicode.org/glossary/#ligature Ligature. A glyph representing a combination of two or more characters. In the Latin script, there are only a few in modern use, such as the ligatures between "f" and "i" or "f and l". Other scripts make use of many ligatures, depending on the font and style. > Is a digraph exactly the same as a ligature, or is there some difference > please? -- ------------------------------------------------------------- Tex Texin cell: +1 781 789 1898 mailto:[EMAIL PROTECTED] Xen Master http://www.i18nGuy.com XenCraft http://www.XenCraft.com Making e-Business Work Around the World -------------------------------------------------------------
