ZnCharacterStreamTests #testUpToAll and #testUpToAllTwice are now failing

[dalehenrich]

These two tests were skipped dating back to my original port of FileSystem to GemStone and today I turned the testing back on and the tests are now failing ... so it is time for me to pay the piper and bring the #upToAll: implementation up to snuff

[dalehenrich]

as of this commit [69e837d], I believe that the #upToAll: implementation is complete, however, there seem to be some issues with the #position method and ZnCharacterReadStream on UTF8 encoded streams:

	| string bytes stream res |
	string := 'eißendeße'.
	bytes := ZnUTF8Encoder new encodeString: string.
	stream := (ZnCharacterReadStream on: bytes readStreamPortable).
	res := stream next; next; next.
	self assert: res equals: $ß.
	self assert: stream position equals: 3.

So will hold off until the issue is resolved..

[dalehenrich]

Issue #80 reports the above problem

[dalehenrich]

Will close this issue in anticipation of Issue #80 resolving the current test failures, but can be re-opened if necessary

I switched implementations of #upToAll: and updated #testUpToAllTwice which was using (Character codePoint: 150) and similar expressions. These are out of range of Unicode7. They cause it to promote to Unicode16, which the 8BitEncoder is not designed to support. I disabled them when the #stringClass is Unicode7.
