  <para>
   Returns the Unicode name for a given property, as given in the Unicode database file PropertyAliases.txt.
  </para>
  <para>
   In addition, this function maps the property <constant>IntlChar::PROPERTY_GENERAL_CATEGORY_MASK</constant> to the
   synthetic names "gcm" / "General_Category_Mask". These names are not in PropertyAliases.txt.

   This function complements <function>IntlChar::getPropertyEnum</function>.

     <para>
      All properties have a long name. Most have a short name, but some do not. Unicode allows for additional names;
      if present these will be returned by adding 1, 2, etc. to <constant>IntlChar::LONG_PROPERTY_NAME</constant>.

   Returns the name, or &false; if either the <parameter>property</parameter> or the <parameter>type</parameter>

  <para>
   If a given <parameter>type</parameter> returns &false;, then all larger values of
   <parameter>type</parameter> will return &false;, with one exception: if &false; is returned for
   <constant>IntlChar::SHORT_PROPERTY_NAME</constant>, then <constant>IntlChar::LONG_PROPERTY_NAME</constant>
   (and higher) may still return a non-&false; value.
