/*
 * Expand_ISO_Accent.bsh - Macro for jEdit that
 * replaces ISO accent character abbreviations
 * with accent characters. The 2-character 
 * abbreviation must be directly to the left of 
 * the caret.
 *
 * By default a space is passed to the text area
 * so this macro can be bound to the SPACE key.
 *
 * Change:
 *
 *   expandISOAccent(view,true);
 *
 * to:
 *
 *   expandISOAccent(view,false);
 *
 * to disable this behavior.
 *
 * Abbreviations taken from:
 *   http://www.cs.tut.fi/~jkorpela/emacs-iso.html
