CodeSnip Old Code (SVN)

* Changed TDBDownloadMgr.GetDatabase to return character set used to encode data stream along with data stream itself.
* Changed TUpdateMgr to pass char set info along to TFileUpdater.
* Changed TFileUpdater to decode stream data using char set passed from TDBDownloadMgr.
* XMLDoc commented UFileUpdater unit.

Changed THTTPEx.GetResponseCharSet to return a default char set name when HTTP response does not include a char set. Previously returned empty string.

Don't want empty string because TWebCharEncodings interprets it differently to TEncodingHelper, so we would get a different encoding for empty char set from each class.

Added new ResponseCharSet property to both THTTPEx and TBaseWebService that returns the character set used for the last HTTP response.

Changed THTTPEx.DoRequestText to use new TWebCharEncodings.FreeEncoding method to free its encoding object.

Small changes to XMLDoc comments.

* Heavily revised TEncodingHelper to enable classes to descend from it that offer only a subset of its supported encodings.
* Completely rewrote TWebCharEncodings to descend from TEncodingHelper.
* Lots of work on XMLDoc comments.

Made minor change to XMLDoc comments.

Replaced call to now removed Windows1252BytesOf routine with code that creates and uses a suitable encoding to perform the same function.

Removed all Windows-1252 helper code: string type, bytes array conversions and associated private helper class.

* Removed Windows1252CodePage and ASCIICodePage constants from UEncodings. They were duplicated by constants in TEncodingHelper.
* Updated affected code in UEncodings and UHTMLTemplate units.
* Improved XMLDoc commenting in UEncodings unit.
