CodeSnip Old Code (SVN)

* Replaced all character set constants and their use with new inline functions to test for required characters, made Unicode safe where required.
* Added shorthand alias constants for TTextStreamReader.EOL and TTextStreamReader.EOF.

Changed IsValidAbsoluteFileName private function in UFileProtocol.pas to use IsValidDriveLetter function from UUtils.pas.

Modified non-Unicode implementation of IsWhiteSpace in UUnicodeHelper.pas to test for white space characters defined in UConsts unit.

* Added new IsValidDriveLetter function.
* Re-implemented ContainsWhiteSpace in a Unicode friendly way.

Used conditional compilation in URTFUtils.RTFMakeSafeText routine to eliminate expression that always evaluates true on non-Unicode Delphis.

Changed TSourcePrefsPreview.Generate to convert highlighted RTF code to ASCIIString from string.

Modified TTaggedTextEntityHandler.TranslateEntity to work with numeric character entities with ordinal value greater than 255.

* Changed all methods in URTFBuilder.pas that accept or return RTF code to use ASCIIString type rather than string.
