(詳細はGreek alphabet that were used in medieval handwritten Greek and in early printing. Ligatures were used in the cursive writing style and very extensively in later minuscule writing. There were many dozens〔(The Philokalia Package ), for LaTeX〕〔Carl Faulmann, ''Das Buch der Schrift: Schriftzeichen und Alphabete aller Zeiten und Völker'', Vienna 1880, p.172-176.〕 of conventional ligatures. Some of them stood for frequent letter combinations, some for inflectional endings of words, and some were abbreviations of entire words. In early printed Greek from around 1500, many ligatures fashioned after contemporary manuscript hands continued to be used. Important models for this early typesetting practice were the designs of Aldus Manutius in Venice, and those of Claude Garamond in Paris, who created the influential Grecs du roi typeface in 1541. However, the use of ligatures gradually declined during the 17th and 18th centuries and became mostly obsolete in modern typesetting. Among the ligatures that remained in use the longest are the ligature Ȣ for ου, which resembles an ''o'' with an ''u'' on top, and the abbreviation ϗ for ('and'), which resembles a κ with a downward stroke on the right. The ου ligature is still occasionally used in decorative writing, while the abbreviation has some limited usage in functions similar to the Latin ampersand (&). Another ligature that was relatively frequent in early modern printing is a ligature of Ο with ς (a small sigma ''inside'' an omicron) for a terminal ος. The ligature for στ, now called stigma, survived in a special role besides its use as a ligature proper. It took on the function of a number sign for "6", having been visually conflated with the cursive form of the ancient letter digamma, which had this numeral function. ==Computer encoding== In the modern computer encoding standard Unicode, the abbreviation has been encoded since version 3.0 of the standard (1999). An uppercase version was added in version 5.1 (2008). A lower and upper case "stigma", designed for its numeric use, is also encoded in Unicode. Letters derived from the ου ligature exist for use in Latin, and for Cyrillic, though not for Greek itself. Some attempts have been made at recreating typesetting with ligatures in modern computer fonts, either through Unicode-compliant OpenType glyph replacement,〔e.g. (【引用サイトリンク】title=GFS Gazis ); (【引用サイトリンク】title=Unicode fonts for ancient scripts )〕 or with simpler but non-standardized methods of glyph-by-glyph encoding.〔e.g. 〕 ; Greek digraphs ; Latin and Cyrillic Ou digraphs 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Greek ligatures」の詳細全文を読む スポンサード リンク
