 * @summary Verifies logical fonts support Indic + other Asian code points
 * @requires (os.family == "windows")
 */

/*
 * This isn't just testing Indic fonts, a few other Asian scripts are
 * also being verified.
 * Oracle JDK for Windows had supported Devanagari and Thai in the logical
 * fonts using a proprietary font, since Windows did not have such fonts.
 * Since that was first added Microsoft added into Windows 7 a
 * number of fonts to support Indic + other Asian scripts.
 * By referencing these in the fontconfig.properties files we can enure that
 * these scripts are supported by the logical fonts when using OpenJDK for
 * Windows.
 * The test here just verifies that at least one required code point from each
 * of these scripts is available to make sure we don't regress, or to catch
 * and understand cases where those fonts may not be installed.
