CodeSnip Old Code (SVN)

* Removed TODO comments that simply documented changes made to compile with Delphi 2010.
* Removed any commented out code.

Delete redundant private IsWhiteSpace routine from UUtils unit. Version in UUnicodeHelper unit now used in preference.

Added routines to UUnicodeHelper unit to safely convert a string to a Latin-1 encoded AnsiString and to check if a character is Latin-1.

Modified code that reads and writes encrypted data to ensure the strings to be encrypted and decrypted are safely converted to the Latin1 code page.

Added Classes to uses cause to permit inlining of TObjectList methods.

Added conditionally defined $WARN directive to switch off warning about explicit string cast from string to ANSI string potentially loosing data. The referenced cast is OK.

* Changed UEncrypt unit's Encode routine to define a character map as an array of AnsiChar instead of Char.
* Commented changes to original unit.

Made implicit casts from AnsiString to UnicodeString to explicit casts in order to document the intention.

* Changed character set testing code in several units to use char set helper functions added to UUnicodeHelper.pas instead of testing directly against literal or constant sets. This prevents Delphi 2010 warnings about WideChar being reduced to byte char in set expressions.
* Changed use of UpCase built-in to use ToUpperCase function added to UUnicodeHelper.pas.
* Added various set handling routines along with ToUpperCase function. These mainly call TCharacter methods on Unicode Delphis and have custom implementations on other Delphis.

Modified TAppInfo.GenerateKey to be Unicode compatible: now uses new ASCIIBytesOf routine (added to UUnicodeHelper unit) to ensure program key contains only ASCII characters.
