   /* Default_Ignorable codepoints:
    *
    * Note that as of Oct 2012 (Unicode 6.2), U+180E MONGOLIAN VOWEL SEPARATOR
    * is NOT Default_Ignorable, but it really behaves in a way that it should
    * be.  That has been reported to the Unicode Technical Committee for
    * consideration.  As such, we include it here, since Uniscribe removes it.
+   * It *is* in Unicode 6.3 however.  U+061C ARABIC LETTER MARK from Unicode
+   * 6.3 is also added manually.  The new Unicode 6.3 bidi formatting
+   * characters are encoded in a block that was Default_Ignorable already.
    *
    * Note: While U+115F and U+1160 are Default_Ignorable, we do NOT want to
    * hide them, as the way Uniscribe has implemented them is with regular
    * spacing glyphs, and that's the way fonts are made to work.  As such,
    * we make exceptions for those two.
