Instance protocol:

 characterSizeChanged: aCharacterOrString

change aCollection to fit the size of aCharacter

 on: aCollection

 on: aCollection from: start to: stop

 with: aCollection

 next: count put: aCharacter

append anObject count times to the receiver.
Redefined to avoid count grows of the underlying collection -
instead a single grow on the final size is performed.

 nextPut: aCharacter

append the argument, aCharacter to the stream.
Specially tuned for appending to String, ByteArray and Array streams.

 nextPutAll: aCollection

append aCollection to the receiver.
Redefined to convert to a string of the needed charcter size.

 nextPutAll: aCollection startingAt: start to: stop

 nextPutAllUnicode: aCollection

 nextPutUnicode: aCharacter

Examples:

    |stream|

    stream := CharacterWriteStream on:(String new:32).
    stream nextPutAll:'abc'.
    stream nextPut:(Character value:16r2c00).
