Any other character in the regular expression is a literal that is compared to a single character in the source string.
myVar01 = "abcdef"; // evaluates as TRUE if (myVar01 like "a_c%") ; end
myVar01 = "ab%def"; // evaluates as true if (myVar01 like "ab\\%def") ; end
myVar01 = "ab%def"; // evaluates as true if (myVar01 like "ab+%def" escape "+") ; end
// evaluates as true if ("hello " like "hello ") ; end
