The following topics are covered:


 * Page 96: UTF-8 Clarification



Page 96: UTF-8 Clarification
On page 96, under the section titled UTF-8, the following corrections can be made to the first paragraph.

Change:

&quot;Universal Transformation Format, 8-bit form (UTF-8) converts a 16-bit Unicode character into a series of from 2 to 5 bytes, with the lead byte detailing how many bytes follow. The number of bytes depends on the value of the particular Unicode character, and all characters with ASCII values (from 0 through 127) are represented in a single byte following the lead byte. UTF-8 is considered fairly efficient, but when searching for a particular character in the middle of a byte stream, one might have to parse backward up to 4 bytes in order to find the start of a character. UTF-8 is also reversible (just like UTF-7); the original Unicode data can be obtained by doing a reverse transformation.&quot;
