CodeSnip Old Code (SVN)

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.
* Changed internal handling of RTF similarly.

Modified to work with revised RTF: now uses ASCIIString type for RTF code rather than string.

* Converted code in URTFUtils.pas to use ASCIIString and AnsiChar types for RTF code rather than string and Char.
* Added support for \u Unicode control.
* RTFMakeSafeText now converts characters with ordinal value > 255 to \u controls.
* Changed RTFControl to take SmallInt rather than Integer parameter for control word.

Added support for ASCII string type to UUnicodeHelper.pas: code page constant, string type and conversion routines.

* Changed MakeSafeHTMLText to encode Unicode characters correctly as HTML entities.
* Changed URLEncode to ensure URL is in latin-1 encoding: URL encoding can only escape single byte characters.
* Replaced call to Chr() function in URLDecode with Char cast.

Replaced printable characters specified in form #xxx with actual character literal. This to avoid cases where Unicode code point for a character is different to Ansi / Latin-1 code point.

* Rationalised TDataStreamWriter code, removing redundant methods.
* Changed Unicode only TDataStreamWriter methods that write strings to specifically use UnicodeString type.
* Revised and completed commenting of TDataStreamWriter.
