A convenience method for determining if a Unicode character may be part of a Java identifier other than the starting character.

A character may be part of a Java identifier if and only if it is one of the following:

• a letter
• a currency symbol (such as "$")
• a connecting punctuation character (such as "_").
• a digit
• a numeric letter (such as a Roman numeral character)
• a combining mark
• a non-spacing mark
• an ignorable control character
