| Returns <code>true</code> if the <code>charCode</code> argument is a high word in a surrogate pair. |
| A surrogate pair represents a character with a code point that requires more |

| of two 16-bit words, a high surrogate and a low surrogate, to embody its code point. |
| <p>This method can be used when processing a series of characters to |
| ensure that you do not inadvertently divide a surrogate pair |
