CodeSnip Old Code (SVN)

* Added new StrCompareText routine to UStrUtils.
* Replaced all calls to AnsiCompareText with StrCompareText.

* Fixed error in TAlphaListPageHTML.BuildRoutineList where snippets with names that started with lower case letters were not being added to the snippets list. This fixes bug #3120962.
* Added Equals operator overloads to TInitialLetter to enable two records or one record and one Char to be compared for equality, ignoring case.
* Modified TAlphaListPageHTML.BuildRoutineList to compare the initial letter of snippet names with the initial letter record of the view using the new Equals operator overload noted above.

Removed now redundant TInitialLetterList class.

* Renamed UAlphabet unit as UInitialLetter and completely rewrote and simplified it.
* Modified units using UInitialLetter unit as necessary re changes.
* Modified TAlphaGroupItem and TAlphaGrouping to accept any upper case Unicode character instead of just "A".."Z" and "_". Uses natural sorting so, for example "Ö" sorts between "O" and "P". Now scans all snippets to build list of initial letters.
