4 * This file contains routines to attempt to add fonts to a font pattern
5 * so that XCreateFontSet will not fail because the given font(s) do not
6 * contain all the characters required by the locale.
8 * The original code was apparently written by Tomohiro Kubota; see
9 * <http://www.debian.org/doc/manuals/intro-i18n/ch-examples.en.html#s13.4.5>.
