ISSUE:       1944
TITLE:       Increase maximum string literal length to 64K (bytes) while setting a lower
  limit (of characters) for multibyte charsets based on their max char. length
  (UTF-8 literals will be limited to 16383 characters)
DESCRIPTION:
  Test verifies that one may to operate with string literals:
  1) containing only ascii characters (and limit for this case should be 65535 bytes (=chars))
  2) containing unicode characters but all of them requires 3 bytes for encoding (and limit for this should be 16383 character)
  3) containing literals with mixed byte-per-character encoding requirement (limit should be also 16383 character).
  Before 3.0.0.31981 following statement raises:
  String literal with 65536 bytes exceeds the maximum length of 32767 bytes
