Description

Call UTF8CharSize to determine the number of bytes that follow a lead UTF-8 character (including the lead byte).  

In UTF-8, each lead character can be followed by a variable number of other characters. This combination of UTF-8 characters is used to encode a single Unicode character.

Note: UTF8CharSize always returns 0, if the given character is not a valid UTF-8 lead byte.
