-   * 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, U+1160, U+3164 and U+FFA0 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 four.
