org.apache.fontbox.ttf.gsub.GsubWorkerForDflt

All Implemented Interfaces:

GsubWorker

public class GsubWorkerForDflt
extends Object
implements GsubWorker

DFLT (Default) script-specific implementation of GSUB system.

According to the OpenType specification, a Script table with the script tag 'DFLT' (default) is used in fonts to define features that are not script-specific. Applications should use the DFLT script table when no script table exists for the specific script of the text being processed, or when text lacks a defined script (containing only symbols or punctuation).

This implementation applies common, script-neutral typographic features that work across writing systems. The feature order follows standard OpenType recommendations for universal glyph substitutions.
