I want to donate this func. it can truncate text on canvas with 3 modes: dots at begin/ at middle of text/ at end of text. Tested in ATTabs demo. Code--

https://github.com/Alexey-T/ATTabs/blob/master/attabs/attabs.pas#L894

char $2026 is ellipsis. Can also use '...' or '..'

Why is there :
  S:= UTF8Decode(Text);
  ...
  Result:= UTF8Encode(S);

Please also look at function ShortDisplayFilename() in unit IDEProcs. It should be moved to LazFileUtils.

Except for more flexible positioning of the '...', this is already available as MinimizeName in FileCtrl, or painting text with TCanvas.TextRect having its TextStyle.EndEllipsis = true.

Why is there : S:= UTF8Decode(Text); ... Result:= UTF8Encode(S);

Seems it can be just "S:= Text", "Result:= S". but I had problems
without UTF8Encode/decode in my apps before. On Windows. It was FPC 2.6.4.

It is more simple..

MinimizeName is different as I see. it uses ExtractFile* heavily for ex. And no option DotsString.
