 Namespace containing Unicode constants.

+var constants = require( '@stdlib/constants/unicode' );
+
+function isValidBmpCharacter( char ) {
+    return char.codePointAt(0) <= constants.MAX_BMP;
+}
+
+// Check if a character is within the BMP:
+console.log( 'Is "𝔸" a BMP character?', isValidBmpCharacter('𝔸') ); // false
+console.log( 'Is "A" a BMP character?', isValidBmpCharacter('A') ); // true
