Description

The class of streams over Unicode strings. It is a subclass of <string-stream>.

The contents: init-keyword is used as the input for an input stream, and as the initial storage for an output stream. If it is a stretchy vector, then it is the only storage used by the stream.

The class supports the same init-keywords as <sequence-stream>.

The start: and end: init-keywords specify the portion of the Unicode string to create the stream over: start: is inclusive and end: is exclusive. The default is to stream over the entire Unicode string.
