Extender Glyph Table

The Extender Glyph table (ExtenderGlyph) lists indices of glyphs, such as Arabic kashidas, that a client may insert to extend the length of the line for justification. The table consists of a count of the extender glyphs for the script (GlyphCount) and an array of extender glyph indices (ExtenderGlyph), arranged in increasing numerical order.

Example 2 at the end of this chapter shows an ExtenderGlyph table for Arabic kashida glyphs.
