How do you invoke TCharHelper

I include the Character unit in my uses clause, but get the warning, Symbol 'ToLower' is deprecated: 'Use TCharHelper'. I use ToLower to do a case conversion on unicode characters.

I can't work out how to include TCharHelper.

Sinisa VukCommented:
if you have char value...
uses System.Character;
  someCh, someOtherCh: Char;

someOtherCh := someCh.ToLower;

//or more complex :-)

if not someCh.IsLower then
  someCh := someCh.ToLower;
