CodeSnip Old Code (SVN)

* Corrected URTFUtils unit's RTFMakeSafeText routine to convert Unicode text to correct code page before writing it. Also corrected bug in code that generated Unicode characters.
* Updated TRTFBuilder to take code page parameter to constructor and to use it when writing code page to document and when writing text. Updated TRTFDocProperties similarly.
* Modified all using units to pass code page to TRTFBuilder constructor.

Added new WideCharToChar routine.

Added new HTML document describing the RSS News Feed to the Docs/FileFormats directory.

Added two new HTML documents describing Saved Files and Test Units to the Docs/FileFormats directory.

Removed unused code that reads and writes text files and streams along with CopyFile routine.

Updated to use TFileIO for writing and reading of text files, instead of routines from UUtils.

* Changed to write units as UTF-8 files if source code can't be stored in default ANSI code page. Still uses ANSI default encoding otherwise.
* Ensured that unit names are valid strings in default ANSI encoding to ensure that unit file names contain no Unicode characters (this can make earlier Delphis fail to find file).

Added new EncodingSupportsString public function.

* Added combo box to display and select required file encoding in Save Source code dialog box. Required revision of dialog box template in resources to make room for new controls.
* Created code to supply supported encodings for each file type and to save files using required encoding to source file output manager and related code.
* Much XMLDoc commenting.

Moved system default encoding to end of TEncodingType enumeration. Reason for this explained in comments to TEncodingType.
