Method	Description
AppendCodePoint ( this s, int c ) : StringBuilder	Appends a unicode code point in the range 0 to 0x10FFFF to StringBuilder in UTF-16.
EndsWith ( this sb, UString what, bool ignoreCase = false ) : bool	Finds out whether the StringBuilder ends with the specified substring.
IndexOf ( this sb, UString searchStr, int startIndex, bool ignoreCase = false ) : int	Gets the index of a substring in a StringBuilder
IndexOf ( this sb, char value, int startIndex ) : int	Gets the index of a character in a StringBuilder
Last ( this str ) : char	Returns the last character of the string
