When a developer uses the StringBuilder or StringBuffer constructor with a single character as an argument, the likely
intention is to create an instance with the character as the initial string value.
However, this is not what happens because of the absence of a dedicated StringBuilder(char) or StringBuffer(char)
constructor. Instead, StringBuilder(int) or StringBuffer(int) is invoked, which results in an instance with the provided
int value as the initial capacity of the StringBuilder or StringBuffer.
The reason behind this behavior lies in the automatic widening of char expressions to int when required. Consequently,
the UTF-16 code point value of the character (for example, 65 for the character 'A') is interpreted as an int
to specify the initial capacity.
