  <meta content="This test checks that a single intra-base white space must be used when doing unit box pairing as long as it does not begin a ruby base container box or it does not end a ruby base container box. In this test, a leading white space inside of a ruby base unit box (the 'c' one) and a trailing white space inside of a ruby base unit box (the 'd' one) are collapsible white spaces across adjacent ruby base boxes according to white space processing rules.">
