Instantiating a StringBuilder or a StringBuffer with a character is misleading because most Java developers would expect
the character to be the initial value of the StringBuffer.
What actually happens is that the int representation of the character is used to determine the initial size of the StringBuffer.
Noncompliant Code Example
StringBuffer foo = new StringBuffer('x'); //equivalent to StringBuffer foo = new StringBuffer(120);
Compliant Solution
StringBuffer foo = new StringBuffer("x");
