TITLE:       SUBSTRING - miscelaneous tests of <str> SIMILAR TO <pattern>
DESCRIPTION:
  Test creates table and fills it with unicode data to be checked (field 'str'), pattern and
  performs output of SUBSTRING( <str> SIMILAR <pattern> ).
  Also, some additional examples presents for other checks.

  Original test see in:
