ReplaceTarget with an empty string leads to an Assertion in SciLexer in Debug Modus

[FilipRychnavsky]

I have a scenario, where I would like to delete some text.

1. I select desired string with TargetStart and TargetEnd.
2. I perform a successful SearchInTarget

3. I call the method ReplaceTarget("") An assert is called from SCI_REPLACETARGET in SciLexer 3.7.2\src\Editor.cxx, because of PLATFORM_ASSERT(lParam); The reason is because text is empty in public unsafe int ReplaceTarget(string text) and it translates to bytes and IntPtr of null.

       public unsafe int ReplaceTarget(string text)
       {
           if (text == null)
               text = string.Empty;
   
           var bytes = Helpers.GetBytes(text, Encoding, false);
           fixed (byte* bp = bytes)
               DirectMessage(NativeMethods.SCI_REPLACETARGET, new IntPtr(bytes.Length), new IntPtr(bp));
   
           return text.Length;
       }

   Here the Editor.cxx

   case SCI_REPLACETARGET:
       PLATFORM_ASSERT(lParam);
       return ReplaceTarget(false, CharPtrFromSPtr(lParam), static_cast<int>(wParam));

   The assertion influences only the debug modus. Everything is fine in release. Greetings Filip Rychnavský
