Applying a computer-implemented test to determine whether to replace adjacent characters in a word with a ligature glyph

摘要

A computer determines whether to use a ligature glyph in place of adjacent non-ligature characters by identifying adjacent characters in a word that can be represented by a ligature glyph, applying a test to determine whether the adjacent characters occur at a position in the word at which the ligature glyph is allowed to appear, and using the ligature glyph in place of the adjacent characters only if the test is satisfied. <IMAGE>
