The UTF-8 string functions handle string operations on UTF-8 encoded strings. This is the default character string data type used for encoded XML data. UTF-8 strings are represented in C as strings of unsigned characters (bytes) to cover the full range of possible single character encodings.
This group of functions encompasses functions for doing conversions to and from UTF-8 to Unicode as well as standard string manipuation functions such as exist in the C standard string library.
For a complete list and full description of all of the UTF-8 string functions, see the XBinder C/C++ Runtime Reference Manual.
