SYMPTOMS

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section of this article.

MORE INFORMATION

A surrogate pair is a pair of 16-bit Unicode code values that represent a single character. The first surrogate is a 16-bit code value in the range U+D800 to U+DBFF. The second surrogate is a 16-bit code value in the range U+DC00 to U+DFFF. Surrogate pairs extend the character set beyond the Unicode characters. By using surrogates pairs, Unicode can support over one million characters. For more information about surrogate pairs, visit the following Microsoft Web site:
