* @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.
