-- fixed bug affecting set_chars and service and its uhandle[n] form. -- and another one in get_chars when unicode.set_base(0) has been called and a 0 pos argument supplied.
-- cleaned up shutdown sequence, so complicated things don't happen when plugin is unloaded or Powerpro terminated. -- empty service abolished; doesn't make sense for unicode strings. -- the raiseErrors value in the configuration ini file and the error_dialog_on/error_dialog_off service were erroneously in the documentation, never implemented. Cleaned up docs to match reality. -- added documentation on surrogate pairs (unicode values outside the "basic multilingual plane"); combining code points, variation selectors, and all the good stuff that can muck up plugin services that change or access characters within unicode strings. -- added test_glyph_type and set_glyph_size_test services to allow unicode strings to be tested for the above. Added script unicodePluginGlyphTypeTests.powerpro to illustrate them. -- added from_num, (aka from_nums), append_fromnum services, both of which can accept unicode values outside the "basic multilingual plane"
