Detailed Description

FXString provides essential string manipulation capabilities in FOX.

Internally, all strings are stored as an array of bytes preceeded by the length of the string; an end-of-string character is appended at the end, but is not included in the length of the string. An empty string is represented by unique empty-string value which comprises a length of 0, followed by an end-of-string character. Thus, it is ALWAYS safe to dereference FXString as it will never be NULL. FXString can be initialized direcly from literal strings in UTF-8 encoding, but supports automatic conversion from UTF-16 encoded ("narrow") character strings and UTF-32 encoded ("wide") character strings.
